Subject: bhyve: support VNC 'wait' attribute
X-Git-Tag: v11.10.0-rc1~70
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5944f566acf6db797c1ebf97ba0d02216953e325;p=thirdparty%2Flibvirt.git

bhyve: support VNC 'wait' attribute

Bhyve supports the 'wait' option for the VNC device configuration.
When enabled, VM boots only upon a VNC connection.

Sample device configuration looks like this:

 -s 29,fbuf,tcp=0.0.0.0:5900,w=800,h=600,wait
