Re: [Xen-devel] [Xen-users] VGA passthough still not working

The more i think about it, the more i remember:

After installing Windows within DomU and after installing the Catalyst Driver, 
i remember disabling the Emulated Cirrus VGA Card within the Device-Manager in 
Windows; don't know exactly anymore, but this could be an important step so 
that the Catalyst Driver "takes over" correctly;

Another hint: To acces the VNC console:

xvncviewer localhost:5910
(if you use the DomU Config pasted)

and of course you need to adapt the DomU Config especially for the first boot - 
to include an ISO Image of the Windows-Install-CD , e.g.:

disk = [ 'phy:/dev/vg_ssd/win7system,hda,w' , 
'file:/path/to/windows.iso,ioemu:hdb,r' ]


would be better while installing Windows
