# NAME

`vmt` — VMware Tools driver

# SYNOPSIS

`vmt0 at pvbus0`

# DESCRIPTION

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 all non-loopback IP addresses to the host.

# SEE ALSO

pvbus(4), init(8), sensorsd(8), sysctl(8)

A vmwh helper program is available via packages(7).

# HISTORY

The `vmt` driver first appeared in OpenBSD 4.4.

# AUTHORS

The `vmt` driver was written by David Gwynne <dlg@openbsd.org>.
