[Bug 656531] [NEW] libvirt unable to start VM with SDL display

[Jamin W. Collins]

Public bug reported:

Since upgrading to 10.10, attempting to start any VM (new or pre-
existing) that utilizes an SDL display fails.  Initially, I thought it
might be something with qemu/kvm.  However, starting a VM with an SDL
display manually with a command like the following, works fine:

kvm -m 512 -cdrom dsl.iso -boot d

I then thought it might be something with my pre-existing VMs
definitions.  So, I created a completely new VM using virt-manager.  As
long as the VM is using a VNC display it starts fine.  However, once the
VNC display is removed and replaced with an SDL display it fails to
start.

Log entries such as the following are created:
