[libvirt] [PATCH] bhyve: add support for video device configuration
by Roman Bogorodskiy 12 Jun '17

12 Jun '17

Connect domain XML <driver vgaconf=""> configuration (introduced in a previous patch) to bhyve command generation. Unfortunately, this option was documented just recently and at the time of writing official online manpages didn't have it updated, so for now one can refer to: https://github.com/freebsd/freebsd/blob/master/usr.sbin/bhyve/bhyve.8#L327 for the detailed description of the possible vga configuration options. Also, add some tests for this new feature.

[libvirt] [PATCH 1/2] conf: add video driver configuration element
by Roman Bogorodskiy 12 Jun '17

12 Jun '17

Add support for video driver configuration. In domain xml it looks like this: <video> <model type=''> <driver .../> </model> </video> At present, the only supported configuration is 'vgaconf' that looks this way: <driver vgaconf='io|on|off'> It was added with bhyve gop video in mind to allow users control how the video device is exposed to the guest, specifically, how VGA I/O is handled.
