Use the command 'bvm --create vmname' to create 117 | 118 | 2. Use an existing VM configuration as template: 119 | 120 | bvm --create newname from template-vmname 121 | 122 | - template-vmname: Name of existing VM (template) 123 | - newname: Name of new VM 124 | This command will copy the template VM's configuration to the new VM for customization. 125 | 126 | Standard templates available: 127 | - freebsd (FreeBSD standard configuration) 128 | - linux (Linux standard configuration) 129 | - windows (Windows standard configuration) 130 | 131 | You can also use any existing VM name as a template. 132 | 133 | Optional parameters for template creation: 134 | -s Set boot type to grub 135 | -U=N Set CPU count (e.g. -U=4) 136 | -m=SIZE Set memory size (e.g. -m=512m, -m=2g) 137 | -d=SIZE Set first disk size (e.g. -d=10g, -d=1t) 138 | -n=MODE Set network mode (bridge or nat) 139 | -i=NIC Set bind NIC (e.g. -i=em0) 140 | 141 | Example: 142 | bvm --create myvm from linux -s -U=4 -m=512m -d=10g -n=bridge -i=em0 143 | 144 | 3. Clone an existing VM: 145 | 146 | bvm --clone oldname newname 147 | 148 | - oldname: Name of existing VM 149 | - newname: Name of new VM 150 | This command will make a complete copy of a VM. 151 | ``` 152 | ### Question 2: How to modify VM configuration? 153 | ``` 154 | Answer: The VM must be powered off, then use command 'bvm --config vmname' to modify settings 155 | Some configuration parameters explained: 156 | 157 | Parameter Description 158 | --------- ----------- 159 | cpus Number of CPUs used by VM (the total vCPU count) 160 | ram Memory allocated to VM (e.g. 512M or 1G) 161 | CD Enable/disable CD-ROM (on/off) 162 | cd numbers Number of CD drives (1-4) 163 | cd(N) iso ISO path for CD N (enter '-' to clear for cd1-cd3) 164 | boot from Boot options (cd0:CD boot/hd0:Hard disk boot) 165 | boot type Boot method (grub: Standard, uefi: UEFI, uefi_csm: UEFI CSM/Legacy BIOS) 166 | TPM (UEFI) Enable TPM 2.0 support (requires UEFI, needed for Windows 11) 167 | shared folder Share host directories with the VM (VirtIO-9P) 168 | VNC Enable/disable VNC display 169 | VNC bind VNC server bind address (default: 0.0.0.0) 170 | VNC port VNC server port number 171 | VNC width/height VNC display resolution 172 | VNC password Optional password for VNC connection 173 | VNC wait Wait for VNC connection before boot 174 | audio Enable HDA audio device 175 | auto boot Auto-start configuration (see bvm --autoboot) 176 | hostbridge CPU architecture (intel:hostbridge/AMD:amd_hostbridge) 177 | disk config Disk configuration (can add/remove disks, set storage interface: ahci-hd/virtio-blk/nvme) 178 | network config Network configuration (Bridge/NAT/Switch modes) 179 | ``` 180 | ### Question 3: How to view VM configuration information? 181 | ``` 182 | Answer: Use 'bvm --vminfo vmname' to view detailed VM information, including VM name, OS, IP address, network mode, disk info, etc. 183 | 184 | Example output: 185 | --------------------------- 186 | Welcome to Bhyve Vm Manager 187 | --------------------------- 188 | name : debian 189 | os type : Debian 190 | ram : 512m 191 | cpus : 1 192 | disk interface : ahci-hd 193 | disk numbers : 1 194 | |-ZFS support : off 195 | |-disk(0) size : 5g 196 | cd status : on 197 | |-iso path : /root/iso/debian-9.3.0-amd64-netinst.iso 198 | boot from : cd0 199 | hostbridge : hostbridge 200 | boot type : grub 201 | auto boot : yes 202 | |-index : 2 203 | |-time : 15 sec. 204 | nic interface : e1000 205 | nic numbers : 1 206 | nic_0 207 | |-network mode : NAT 208 | |-wan : em0 209 | |-gateway : nat2 [GW 192.168.1.1/24] 210 | |-redirect : disable 211 | |-bridge : bridge1 212 | |-tap : vmnet1 213 | |-ip : 192.168.1.10/24 214 | status : off 215 | lock : no 216 | crypt : no 217 | ``` 218 | ### Question 4: How to start a VM? 219 | ``` 220 | Answer: Use command 'bvm --start vmname' to start, use 'bvm --restart vmname' or 'bvm --reboot vmname' to restart. For VMs using GRUB boot mode, use 'bvm --login vmname' to log in. For UEFI boot mode, 'bvm --login' can be attempted, but console login support depends on the guest OS configuration; if it fails, please use VNC or SSH. 221 | ``` 222 | 223 | ### Question 5: What is VM auto-start and how to use it? 224 | ``` 225 | Answer: VM auto-start means automatically starting VMs when the system boots. For example: with two VMs, vm1 and vm2, where vm1 is a database server and vm2 is a web server that depends on vm1's database service, vm1 must start before vm2. In vm1 and vm2's configurations, there are options like: 226 | 227 | vm1's config: 228 | [8]. auto boot : yes 229 | [9]. boot index : 1 230 | [a]. boot time : 60 231 | 232 | vm2's config: 233 | [8]. auto boot : yes 234 | [9]. boot index : 2 235 | [a]. boot time : 15 236 | 237 | Where [8] indicates auto-start, [9] indicates start order, [a] indicates start delay. 238 | This means vm2 will start 60 seconds after vm1, and if there's a vm3, its start time depends on vm2's boot time value. 239 | 240 | To properly use this option, add to startup script: 241 | sysrc bvmd_enable=yes 242 | 243 | When system boots, it will automatically start all VMs set for auto-start in order, or you can manually start with: 244 | bvm --autoboot 245 | 246 | You can also check auto-start VM settings anytime: 247 | bvm --abinfo 248 | 249 | Example output: 250 | --------------------------------- 251 | idx vm time(sec) 252 | --------------------------------- 253 | 1 freebsd 18 254 | 2 debian 15 255 | ``` 256 | ### Question 6: How to shut down a VM? 257 | ``` 258 | Answer: There are two ways: 259 | 260 | 1. Normal shutdown: 261 | bvm --stop vmname 262 | 263 | 2. Force shutdown (use when VM cannot shut down normally): 264 | bvm --poweroff vmname 265 | ``` 266 | ### Question 7: How to view VM list? 267 | ``` 268 | Answer: There are two formats - long and short: 269 | 270 | - Short list: 271 | bvm --ls 272 | 273 | - Long list: 274 | bvm --ll 275 | Both show VM name, status, OS, IP address etc. 276 | 277 | You can also use parameters to get specific information: 278 | 279 | - Online list: 280 | bvm --ls online 281 | 282 | - By status: 283 | bvm --ls bystatus 284 | 285 | - By OS: 286 | bvm --ls byos 287 | 288 | - By IP: 289 | bvm --ls byip 290 | ``` 291 | ### Question 8: How to lock VMs? 292 | ``` 293 | Answer: Sometimes you need to prevent accidental VM deletion by using the lock feature. When locked, VMs cannot be deleted until unlocked. 294 | 295 | bvm --lock vmname 296 | bvm --unlock vmname 297 | bvm --lockall 298 | bvm --unlockall 299 | ``` 300 | 301 | ### Question 9: VM encryption and decryption operations 302 | ``` 303 | Answer: For security, some VMs need encryption when powered off to prevent unauthorized use of VM files. Encrypted VMs cannot start until decrypted. Note that encryption and decryption require the same password; if the password is lost, it cannot be decrypted. Starting from bvm 1.3.4, due to the modified encryption algorithm, old encrypted VMs cannot be decrypted; you need to decrypt them with an old version first, then encrypt them with a new version. 304 | 305 | VM encryption/decryption is done with these commands: 306 | 307 | bvm --encrypt vmname 308 | bvm --decrypt vmname 309 | ``` 310 | ### Question 10: How to check VM network status? 311 | ``` 312 | Answer: Use ‘bvm --netstat’ command to view online VM network status, including network mode, IP address, gateway, port forwarding, bridge, TAP etc. 313 | 314 | Example output: 315 | NAME NIC MODE IP GATEWAY PORTS BRIDGE TAP 316 | ob 0 NAT dhcp 172.16.1.1/24 (nat0) - bridge0 vmnet0 317 | c 0 NAT dhcp 172.16.1.1/24 (nat0) - bridge0 vmnet1 318 | freebsd-14 0 NAT 172.16.1.10/24 172.16.1.1/24 (nat0) tcp 22:2224 bridge0 vmnet3 319 | ``` 320 | 321 | ### Question 11: How to view network device information? 322 | ``` 323 | Answer: You can use these commands to view network device information: 324 | 325 | bvm --showdev 326 | bvm --showdevall 327 | bvm --showdevuse 328 | 329 | Example output: 330 | default-bridge 331 | |-em0 332 | |-c (nic1) 333 | |-test (nic1) 334 | nat0 [172.16.1.1/24] 335 | |-ob (nic0) 336 | |-c (nic0) 337 | |-c11 (nic0) 338 | |-c12 (nic0) 339 | |-centos (nic0) 340 | |-test (nic0) 341 | |-freebsd-14 (nic0) 342 | nat1 [10.10.30.1/24] 343 | |-null 344 | nat2 [192.168.1.1/24] 345 | |-c2 (nic0) 346 | |-debian (nic0) 347 | switch0 [10.0.1.0/24] 348 | |-null 349 | switch1 [10.0.2.0/24] 350 | |-null 351 | switch2 [10.0.3.0/24] 352 | |-null 353 | switch3 354 | |-null 355 | switch4 356 | |-null 357 | switch5 358 | |-null 359 | switch6 360 | |-null 361 | switch7 362 | |-null 363 | 364 | The default-bridge is the default VM-host bridge; nat0-nat2 are 3 reserved NAT interfaces for host communication; switch0-switch7 are 8 reserved VM communication interfaces, which are also bridges but differ from the default bridge as they're mainly for internal networking and usually don't include host physical NICs. 365 | ``` 366 | ### Question 12: What network modes does bvm have? 367 | ``` 368 | Answer: bvm provides bridge and NAT modes, with 3 reserved NAT interfaces for host communication and 8 switch interfaces for host communication. Administrators can set NAT network IP addresses as needed, switches usually don't need configuration except in special cases. 369 | 370 | NAT configuration is in /usr/local/etc/bvm/nat.conf, defined as: 371 | 372 | nat0=172.16.1.1/24 373 | nat1=10.10.30.1/24 374 | nat2=192.168.1.1/24 375 | 376 | Switch configuration is in /usr/local/etc/bvm/switch.conf, defined as: 377 | 378 | switch0=10.0.1.0/24 379 | switch1=10.0.2.0/24 380 | switch2=10.0.3.0/24 381 | switch3= 382 | switch4= 383 | switch5= 384 | switch6= 385 | switch7= 386 | 387 | bvm provides commands to manage NAT and switch interfaces: 388 | 389 | Query commands: 390 | 391 | bvm --natinfo 392 | bvm --swinfo 393 | 394 | Setting commands: 395 | 396 | bvm --setnat 397 | bvm --setsw 398 | bvm --unsetsw 399 | 400 | Add commands: 401 | 402 | bvm --addnat 403 | bvm --addswitch 404 | 405 | Delete commands: 406 | 407 | bvm --delnat 408 | bvm --delswitch 409 | ``` 410 | 411 | ### Question 13: What is port forwarding? 412 | ``` 413 | Answer: Port forwarding maps internal VM ports to host ports, enabling VM-host communication. bvm allows setting port forwarding during VM creation and configuration. Additionally, bvm supports dynamic port forwarding to add/remove rules without stopping VMs, using commands: 414 | 415 | bvm --setpr 416 | bvm --showpr 417 | 418 | For example, to set port forwarding for a VM with IP 192.168.1.10: 419 | 420 | bvm --setpr 192.168.1.10 421 | 422 | You can view port forwarding rules anytime: 423 | 424 | bvm --showpr 425 | 426 | Example output: 427 | PROTO VM IP:PORT HOST PORT VM NAME 428 | tcp 172.16.1.10:22 2224 freebsd-14 429 | tcp 172.16.1.10:80 8080 freebsd-14 430 | ``` 431 | ### Question 14: How to view DHCP client information? 432 | ``` 433 | Answer: Use ’bvm --showdhcp‘ command to view online VM DHCP client information, including VM name, MAC address, IP address, lease time etc. 434 | 435 | Example output: 436 | ip mac bind_time status 437 | -- --- --------- ------ 438 | 172.16.1.100 00:a0:98:ad:89:74 03/26 09:30:37 - 03/26 19:30:37 ASSOCIATED 439 | 192.168.1.100 00:a0:98:dc:ff:5b 03/26 09:34:26 - 03/27 09:34:26 ASSOCIATED 440 | 441 | ``` 442 | ### Question 15: How to configure DHCP? 443 | ``` 444 | Answer: The DHCP configuration file is located at /usr/local/etc/bvm/dhcp.conf, where you can modify the nat0-nat2 parameters as needed. 445 | 446 | Static IP addresses should be written in the following format: 447 | 448 | nat0_static_ip_01="172.16.1.2 00:00:00:00:00:00" 449 | nat0_static_ip_02="172.16.1.3 00:00:00:00:00:00" 450 | 451 | Dynamic IP range should be written in the following format: 452 | 453 | nat0_dynamic_ip="172.16.1.100 172.16.1.254" 454 | 455 | Other sections can be filled in according to the default configuration. 456 | ``` 457 | ### Question 16: How to view VM CPU, memory, network traffic information? 458 | ``` 459 | Answer: Use 'bvm --showstats vmname' command to view VM CPU, memory, network traffic information. 460 | 461 | Example output: 462 | [ Infrastructure Metrics ] 463 | CPU Usage : 0.00% (Allocated: 1 Cores) 464 | Memory Usage : 0.97% (Allocated: 2g, Active: 19.89 MB) 465 | Disk I/O & Cap : 466 | - disk0 : Cap: 5g, Used: 1.82 GB (/var/vm/fb/disk.img) 467 | Network Traffic: 468 | - vmnet0 : RX: 726 B / TX: 4.43 KB (Drops: 0) 469 | 470 | [ Advanced VM Stats ] 471 | VM Exits : 1437238 (Rate: ~45784/sec) 472 | - IO Access : 202732 473 | - Emulation : 685290 474 | - Interrupts : 45059 (NMI: 0) 475 | 476 | [ Availability & Services ] 477 | PID : 6044 478 | Host Load Avg : 1.44, 1.43, 1.36 479 | Status : Online 480 | Uptime : 52:34 (Process) 481 | Boot Time : 31s (CPU Runtime) 482 | VNC Service : Disabled 483 | ``` 484 | 485 | ### Question 17: How to use file sharing (Shared Folder)? 486 | ``` 487 | Answer: Shared folders allow you to share host directories with virtual machines. Enable 'shared folder' in the VM configuration, set the share name and host path. 488 | 489 | Configuration options: 490 | shared folder Enable/disable file sharing (on/off) 491 | share name Name used in guest to identify the share 492 | share path Host directory path to share 493 | share ro Read-only mode (on/off) 494 | 495 | Mount in Linux guest: 496 | mkdir -p /mnt/hostshare 497 | mount -t 9p -o trans=virtio hostshare /mnt/hostshare 498 | 499 | Note: VirtIO-9P is well supported in Linux guests. FreeBSD 14 guests lack the virtio_p9fs module; FreeBSD 15+ has full support. 500 | ``` 501 | -------------------------------------------------------------------------------- /bvm.8: -------------------------------------------------------------------------------- 1 | .Dd December 14, 2025 2 | .Dt BVM 8 3 | .Os 4 | .Sh NAME 5 | .Nm bvm 6 | .Nd "Bhyve Virtual machines Management tool" 7 | .Sh SYNOPSIS 8 | .Nm 9 | .Cm --help 10 | .Nm 11 | .Cm --version 12 | .Pp 13 | .Nm 14 | .Cm --create 15 | .Ar name 16 | .Op Cm from Ar template-name Op Fl s | Fl U Ns = Ns Ar N | Fl m Ns = Ns Ar SIZE | Fl d Ns = Ns Ar SIZE | Fl n Ns = Ns Ar MODE | Fl i Ns = Ns Ar NIC 17 | .Nm 18 | .Cm --config 19 | .Ar name 20 | .Nm 21 | .Cm --vminfo 22 | .Ar name 23 | .Nm 24 | .Cm --showstats 25 | .Ar name 26 | .Nm 27 | .Cm --os 28 | .Pp 29 | .Nm 30 | .Cm --ls 31 | .Op Ar byname | byos | bystatus | online 32 | .Nm 33 | .Cm --ll 34 | .Op Ar byname | byip | byos | bystatus | online 35 | .Nm 36 | .Cm --login 37 | .Ar name 38 | .Nm 39 | .Cm --start 40 | .Ar name 41 | .Nm 42 | .Cm --restart 43 | .Ar name 44 | .Nm 45 | .Cm --reboot 46 | .Ar name 47 | .Nm 48 | .Cm --stop 49 | .Ar name 50 | .Nm 51 | .Cm --poweroff 52 | .Ar name 53 | .Nm 54 | .Cm --set-hd-boot 55 | .Ar name 56 | .Pp 57 | .Nm 58 | .Cm --clone 59 | .Ar name new-name 60 | .Nm 61 | .Cm --remove 62 | .Ar name ... 63 | .Nm 64 | .Cm --rename 65 | .Ar name new-name 66 | .Pp 67 | .Nm 68 | .Cm --encrypt 69 | .Ar name 70 | .Nm 71 | .Cm --decrypt 72 | .Ar name 73 | .Pp 74 | .Nm 75 | .Cm --lock 76 | .Ar name 77 | .Nm 78 | .Cm --unlock 79 | .Ar name 80 | .Nm 81 | .Cm --lockall 82 | .Nm 83 | .Cm --unlockall 84 | .Pp 85 | .Nm 86 | .Cm --addisk 87 | .Ar name 88 | .Nm 89 | .Cm --deldisk 90 | .Ar name 91 | .Pp 92 | .Nm 93 | .Cm --abinfo 94 | .Nm 95 | .Cm --autoboot 96 | .Pp 97 | .Nm 98 | .Cm --reload-nat 99 | .Pp 100 | .Nm 101 | .Cm --setnat 102 | .Ar Nat ip/mask 103 | .Nm 104 | .Cm --setsw 105 | .Ar Switch ip/mask 106 | .Nm 107 | .Cm --unsetsw 108 | .Ar Switch 109 | .Pp 110 | .Nm 111 | .Cm --setpr 112 | .Ar ip 113 | .Nm 114 | .Cm --showpr 115 | .Pp 116 | .Nm 117 | .Cm --showdhcp 118 | .Pp 119 | .Nm 120 | .Cm --showdev 121 | .Nm 122 | .Cm --showdevuse 123 | .Nm 124 | .Cm --showdevall 125 | .Pp 126 | .Nm 127 | .Cm --snapshot 128 | .Ar name 129 | .Nm 130 | .Cm --rollback 131 | .Ar name 132 | .Nm 133 | .Cm --showsnap 134 | .Ar name 135 | .Nm 136 | .Cm --showsnapall 137 | .Pp 138 | .Nm 139 | .Cm --netstat 140 | .Pp 141 | .\" ============ DESCRIPTION ============= 142 | .Sh DESCRIPTION 143 | The 144 | .Nm 145 | is a 146 | .Xr bhyve 8 147 | virtual machine management tool based on FreeBSD that 148 | allows you to easily manage virtual machines. 149 | .Pp 150 | The virtual machine's network is handled by one or more virtual switches. 151 | Each switch has a simple name, which is stored in the corresponding 152 | configuration file and can be modified by the 153 | .Nm 154 | create one or more 155 | .Xr bridge 4 156 | devices for each virtual switch and dynamically assign them to the 157 | virtual machine 158 | .Xr tap 4 159 | interface. When the virtual machine is shut down normally, the 160 | .Nm 161 | will automatically clean up the useless network devices. 162 | .Pp 163 | The 164 | .Nm 165 | supports multiple network cards and multiple hard disks. 166 | Each virtual machine can have multiple network cards or multiple hard disks, 167 | and can easily add, delete, and modify network cards or hard disks. 168 | .\" ============ BASIC SETUP ============ 169 | .Sh BASIC SETUP 170 | Once 171 | .Nm 172 | is installed, the first thing you have to do is set up the virtual 173 | machine's storage directory. 174 | .Pp 175 | Edit the value of 176 | .Pa vmdir 177 | in 178 | .Pa /usr/local/etc/bvm/bvm.conf 179 | .Bd -literal -offset indent 180 | vmdir=/your/vm/dir/ 181 | .Ed 182 | .Pp 183 | If you want to automatically boot the specified list of virtual machines 184 | in order while the host is booting, add the following 185 | lines to 186 | .Pa /etc/rc.conf 187 | to enable: 188 | .Bd -literal -offset indent 189 | bvmd_enable="YES" 190 | .Ed 191 | .\" ============ OPTIONS ============= 192 | .Sh OPTIONS 193 | .Bl -tag -width indent 194 | .It Cm --abinfo 195 | Show information for all auto-bootstrap virtual machines. 196 | .It Cm --addisk Ar name 197 | Add a hard disk to the virtual machine. 198 | .It Cm --autoboot 199 | Start the automatic booting virtual machine in order. 200 | Boot option, which is usually not required in administrator manual 201 | maintenance mode. Sometimes the host is powered on again after shutdown 202 | or unexpected downtime. 203 | At this time, the administrator-set virtual machine can be automatically 204 | started by the rc script. The method is to use 205 | .Nm Cm --config 206 | to modify the default value of the auto boot menu to yes. 207 | 208 | In self-start mode, 209 | .Nm 210 | will refer to the boot level and delay options of vm. The boot level is 211 | the boot priority. When there are multiple self-starting virtual machines, 212 | the lower the startup priority, the more the virtual machine starts. 213 | Back to front. Boot time (boot time) 214 | After starting the current virtual machine, it can also be said that 215 | the number of seconds is tentative before starting the next virtual machine. 216 | The reason for designing these two parameters is because some services may 217 | need to be activated first to ensure normal business. 218 | 219 | For example, the relationship between the database and the web service, 220 | if the data virtual machine library is not prioritized, 221 | it may cause the web service to be abnormal! 222 | 223 | The correct way to use this option is to add the startup script: 224 | .Bd -literal -offset indent 225 | # sysrc bvmd_enable=yes 226 | .Ed 227 | .It Cm --clone Ar name Ar new-name 228 | Clone a new virtual machine from an existing virtual machine. 229 | .It Cm --config Ar name 230 | Edit the configuration of the virtual machine. 231 | This option needs to be used in the case of a virtual machine. Options that 232 | allow users to configure independently are: cpus, ram, iso path, boot from, 233 | hostbridge, uefi, TPM, VNC settings, shared folder, audio, auto boot, disk config, and network config. 234 | .Bl -tag -width 17n 235 | .It cpus 236 | The total number of virtual CPUs used by the current virtual machine. 237 | .It ram 238 | The size of the memory requested by the current virtual machine, 239 | the unit of which can be M/G, etc. 240 | .It iso path 241 | The directory where the iso disc image is located (is the directory, 242 | non-iso absolute address). When the directory is specified, 243 | .Nm 244 | will automatically list the iso files contained in the current directory. 245 | The user can select the menu number. 246 | .It boot from 247 | This is an important option. When the system is first installed, 248 | .Nm 249 | will automatically adjust this option to hd0 for system startup. 250 | When you need to use iso disc for system maintenance, you can change 251 | this option to cd0. 252 | .It CD 253 | Enable or disable CD-ROM support (on/off). 254 | .It "cd numbers" 255 | Number of CD-ROM drives (1-4). Multiple CDs are useful for scenarios 256 | like Windows driver installation. 257 | .It "cd(N) iso" 258 | ISO path for CD N.
