Fedora xen - Jan 2008 - How to change resolution above 1024x768 in guess OS?

RHEL 5 XEN
Virtualized guest is RHEL 3WS.

I can only get 1024x768 for max resolution in the guest.   I have 1600x1200
for real-estate on the monitor. I am using Virt-manager and getting the
screen for there.  If I crank up the resolution in my guest, it seems to
stop at 10x24x768(24 bit color )
This is using VNC to connect right?  Is there a config for that to set
connection resolution size?
The client is seen to have a cirrus logic video card with 8 Megs of RAM.

Anyone know a way to change this or to force at least 1280x1024 ( I would
prefer 1600x1200 )

Assistance appreciated!

Hi Mark,

I don''t think you can get a higher resolution with the virtual graphics
adapter. My suggestions:

- Use a vnc based server inside the DomU
- Use Nomachine NX or FreeNX (suggested if you''re away from the
machine)
- Use XDMCP (suggested if you''re on the same machine)

Good luck!

Emre

You can''t do it -- the problem is a limitation in the emulated Cirrus 
Logic graphics card.  I think the max you''ll ever get is 1280x1024 in
16

As another reply suggested, you could try running a headless X server + 
a VNC server inside the guest.  Or simpler is just to ''ssh -Y
...'' into
the guest and run X programs directly, assuming the guest is running 
some sort of Un*x.
