vmt
— VMware Tools
driver
vmt0 at pvbus0
The vmt
driver is a kernel level
implementation of VMware Tools. VMware Tools are intended to provide better
support for operating systems running inside virtual machines.
vmt
handles shutdown and reboot requests
from the host by signalling
init(8) with
SIGUSR2
and SIGINT
respectively. vmt
will log notifications that the
guest has been suspended or resumed by the host. It also provides access to
the host machine's clock as a timedelta sensor.
vmt
reports the guest's hostname and first
non-loopback IP address to the host.

A vmwh helper program is available via packages(7).
The vmt
driver first appeared in
OpenBSD 4.4.
The vmt
driver was written by
