Thanks
Today I tried WindowsXP domU, and I downloaded the latest intel gma4500
driver, but it seems the same problem. Just in the while after booting
up, domU was working OK, then the system seems very slow on screen
update.
I ssh to the dom0, there was no any symptoms, no any errors log.
Would someone like to give me some instructions to switch some debug
flags on to collect the debugging log?
I personally think that, for desktop application the VGA passthrough is
the only reason to use XEN.
If it's not mature and and stable. I would like to use KVM which is
pretty easy to use , stable, and almost with the same performance.
Thanks
