Subject: XP guests sluggish after around 1 week of uptime
Date: Mon, 12 Jan 2009 04:12:15 +0000 (UTC)	[thread overview]
Message-ID: <loom.20090112T033751-227@post.gmane.org> (raw)

If this is the wrong place to ask this question, please let me know.

I’m running kvm-80 on ubuntu 8.04 x64 kernel 2.6.24-22-server, md raid 5 with
LVM.  When my host is first booted my windows XP guest runs fine, but after
around a week or so of uptime, they start to run very sluggish.  It takes around
a minute just to open the start menu.  

I'm starting to wonder if it is a problem with kvm (qemu) disk performance.  The
Read/Write speeds seems to be half as fast as my VMWare XP guest.  But not sure
why this would happen after running fine for around a week.

I have the XP guest set to use 2GB of ram and disabled the paging file but that
still doesn’t help.



Any advice on troubleshooting this would be appreciated.

Thanks,

-J
