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.
Rich.
