Hello virtual friends. I''m using Windows HVM on CentOS 5.1, xen 3.1. When I conect VNC to Dom0 IP , I get correct screen, main windows console. But I have a very very poor mouse performance. I tried xensoure 4.1 , and I saw a mouse performance a little bit better than xen 3.1 w / CentOS 5.1. What is me problem, CentOS 5.1 or xen 3.1 , or compilation wrong maked by CentOS people. Why xensource vnc performance is better than xen 3.1 ? Thank any help.

Why xensource vnc performance is better than xen 3.1 ?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.
