[Qemu-devel] a user here - pci-assign VGA

[lejeczek <peljasz@yahoo.co.uk>]

hi there, I wanted to share some fairly good news
a while ago when as was battling the problem - pci-assign a 
vga - I got it to work
I realized that it might have worked from the beginning, anyhow,
for me it works now with qemu-kvm 1.2 (which is fedora alpha 
rpm-rebuilt on SL 6.3) with various AMD vgas
but! (there is always a but, isn't there :) )
guest loses vnc?? meaning that VNC gets only blank(black 
screen (this was what deceived me earlier))
whereas guest seems to fine itself, I can rdp to it (it's 
win7), I can get it on a directly attached monitor via 
keyboard + mouse attached in the same fashion
only win device manager shows "Standard VGA Graphic Adapter" 
exclamation marked. (I tied both -vga cirrus and -vga std)

would anybody know how to fix/troubleshoot it?
many thanks
