Before using this option, you need to install `ovftool`.
### VNC port discovery
Packer needs to decide on a port to use for VNC when building remotely. To find
an open port, we try to connect to ports in the range of `vnc_port_min` to
`vnc_port_max`. If we notice something is listening on a port in the range, we
try to connect to the next one, and so on until we find a port that has nothing
listening on it. If you have many clients building on the ESXi host, there
might be competition for the VNC ports. You can adjust how long packer waits
for a connection timeout by setting `PACKER_ESXI_VNC_PROBE_TIMEOUT`. This
defaults to 15 seconds. Set this shorter if vnc connections are refused, and
set it longer if Packer can't find an open port. This is intended as an
advanced configuration option. Please make sure your firewall settings are
correct before adjusting.
