vmd
is a daemon responsible for the
execution of virtual machines (VMs) on a host. vmd
is typically started at boot time and is controlled via
vmctl(8).
To have vmd
enabled at boot time, use
“rcctl enable vmd”, which sets
vmd_flags=""
in rc.conf.local(8).
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
vmm(4).
vmd
is also responsible for proxying
various other commands/requests from
vmctl(8), such as stopping VMs, and
retrieving information from vmm(4) about
running VMs.
The options are as follows:
-D
macro=value-d
-f
file-n
-v
-v
options increase the
verbosity.The vmd
command first appeared in
OpenBSD 5.9.
