In the 'Virtual Hardware details', it lists the model as 'cirrus' with 9MB of RAM. The RAM field cannot be changed, but how to increate the video RAM? My host OS is RH6 and gust OS is Fedora16.

EDIT: From guest OS, when I run xvinfo it displays 'no adaptors present'.

I was trying to play a video using gstreamers xvimagesink plugin (XFree86 video output plugin using Xv extension). The problem is that xvimagesink is using hardware acceleration for video performance and hence the error Could not initialize Xv output.

I guess I'll have to configure hardware acceleration for the guest.

What's your outer problem? Why do you want to increase the video memory? –  David Schwartz Jan 4 '12 at 5:34
    
can you explain the use case? 9Mb of RAM, or 900 - will not make a difference if you want to play games in the VM –  dyasny Jan 4 '12 at 14:16
    
The outer problem is that inside my guest I run xvinfo which displays 'no adaptors present'. I was attempting to play a video using gstreamer. How would I go about configuring my guest to support that? –  Dejan Jan 4 '12 at 16:26

Should be as easy as virsh edit DOMAIN and changing vram attribute of /domain/devices/video/model:

...
<video>
  <model type='cirrus' vram='9216' heads='1'/>                                                            
  <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
</video>
...
