RE: [Xen-users] Mouse pointer - slow response

["Dustin Henning" <Dustin.Henning@xxxxxxxxxxx>]

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).
        Dustin

Hi Dustin,


This only happens when domU (guest) is running.  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.
