Does xen-4.2.0 support VGA passthrough with the virtual machine created by xl command?
Hi, everyone!
I am working on xen-4.2.0 with spice remote connect. My host is Fedora 14
and guest is win7.
I have installed spice package and now I can connect to guest by spice
client.
For better graphics experience, I want to try the VGA passthrough.
With spice tool, I have to create a VM by xl command, and now I am
wondering if it supports VGA passghrouth?
If so, how should I test it ?
