In what way is the performance improved?
One optimisation that is worth doing on Open Source Xen is to make sure you
have enabled usbdevice='tablet' in the domain's configuration file.
This makes the guest use an emulated graphics tablet as the pointing device.
This provides much better tracking of the mouse pointer and makes it possible
to use "grabless" operation: the guest pointer follows your mouse to the edge
of the guest window. When you bright the mouse back into the guest window,
the pointer immediately jumps to the right place.
It could be that CentOS Xen hasn't automatically set this option, where
XenEnterprise has.
Cheers,
