virtual machine daemon
vmd is a daemon responsible for the
execution of virtual machines (VMs) on a host.
is typically started at boot time and is controlled via
vmd enabled at boot time, use
“rcctl enable vmd”, which sets
vmd interfaces with the virtual machine
monitor (VMM) built into the kernel. One instance of
vmd will be spawned for each VM running on the host,
plus extra instances for control operations. Each child
vmd will in turn create one or more VCPU (virtual
CPU) threads responsible for driving the VM's operations using
vmd is also responsible for proxying
various other commands/requests from
such as stopping VMs, and retrieving information from
The options are as follows:
- Define macro to be set to value on the command line. Overrides the definition of macro in the configuration file.
- Do not daemonize and log to stderr.
- Specify an alternative configuration file. The default is /etc/vm.conf.
- Configtest mode. Only check the configuration file for validity.
- Verbose mode. Multiple
-voptions increase the verbosity.
- Default BIOS boot image. The BIOS is an external firmware file that is distributed separately due to an incompatible license. A prepackaged version of the firmware can be installed using fw_update(8).
- Default configuration file. This is optional.
- UNIX-domain socket used for communication with vmctl(8).
