I=E2=80=99m 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 a= fter around a week or so of uptime, they start to run very sluggish. It tak= es around a minute just to open the start menu. =20 I'm starting to wonder if it is a problem with kvm (qemu) disk performa= nce. 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=E2=80=99t help. Any advice on troubleshooting this would be appreciated. Thanks, -J
