Or maybe it requires directdraw?
I was attempting to resume an x2go session http://i.imgur.com/fu9FiIJ.png "Failed to restore all the required visuals. Can't resume the NX session on the display."
I was however able to start a new session to a different x2goserver: http://i.imgur.com/SVJzbg0.png
The x2goclient is running on a windows 7 SP1 32-bit VM (with all available "recommended" and "important" windows updates, but not the 3 "optional" updates) hosted on Fedora 20 64-bit's Virt-Manager.
I am connecting to the Windows 7 VM via-virt-viewer 0.6.0 with SPICE and 32-bit color.
Whether you're using virt-viewer over the network or you're accessing the VM directly on the host through virt-manager, there is no support for 3D acceleration currently. (Red Hat's spice devs are working on 3D acceleration.) http://i.imgur.com/cltbP7C.png
