Description amturnip 2010-11-28 19:01:39 UTC 
Description of problem:

The libvirt XML documentation about video devices (http://libvirt.org/formatdomain.html#elementsVideo) says, "If acceleration should be enabled (if supported) using the accel3d and accel2d attributes in the acceleration element."

It is unclear what "if supported" means. For example,

 * If supported by some version of libvirt?
 * If supported by the host?
 * If supported by the guest operating system?
 * If supported by the vnc/sdl/etc. kind of graphics element?
 * If supported by some computer that tries to display the console?
 * If supported by the hypervisor's emulator of the specified device model, e.g., cirrus?
