Hi folks, Mouse pointer seems slow responding to natvigating when domU is running. But it happens only a while occasionally then coming back normal. It won''t happen when domU shutdown. I have 4G RAM onboard which went through memtest 2 days ago. Please advise where I have to check and how to fix this problem B.R.

Stephen, I believe I experienced this problem in F7 when taking too much memory from dom0. You might try leaving more memory for dom0 and see if that makes a difference. Also, as I had another mouse problem that confused the issue for me, I will mention that I use a Linksys KVM that will take the direction of the mouse and keep sending it even after the mouse stops moving (or changes direction, even completely reversing). This seemed to happen to me a lot more when I was using Xen than not, so I thought it was Xen problem, but eventually I had the same thing happen in linux w/out Xen and then even in Windows.

After shutting it down the jerking/vibrating of mouse pointer stops. I only allot 32M RAM to each domU and there are 6 of them created. In seldom occasion I run all of them concurrently. There are 4G RAM on board. I think it has more than sufficient RAM for dom0. All domU are without GUI except dom0 which runs GNOME desktop. I suspect whether it would be the problem on Xen. But I can''t find out the cause. I don''t know when it will happen. The duration is short then it becomes normal. B.R.

Stephen, Indeed, that does sound like more than sufficient RAM for dom0, even with all domUs running. My only other thoughts would be as follows: 1) You may want to provide more system information for those on the list (Linux Distro, Version, Xen install method, versions). 2) You may want to provide more hardware information for those on the list (# of physical CPUs/Cores, # of vCPUs in dom0 / per domU). 3) You might also search the Internet as well to see if you can find any bug reports that match up with your version(s). 4) Have you checked the load on the dom0/domU(s) when this is happening (xm top / xentop and top on the dom0)? 5) Is mouse USB or PS/2? Have you tried the other type (not a fix, but might narrow down the problem).
