[Xen-users] XP SP3 guest high CPU usage

[David <admin@xxxxxxxxxxx>]

Hi I'm getting very high CPU usage on idle for an XP SP3 guest, which is doing nothing and is reporting 0% CPU within the guest.

as you can see i have 2 server 2003 domains also which are behaving a lot better, all windows domains have GPLPV(latest).




memory = 256
vcpus=1
name = "windowsxpsp3"
vif = [ 'bridge=eth1' ]
disk = ['phy:/dev/Xen-Test/windowsxpsp3-2,hda,w','tap:aio:/mnt/WinXPSP3.iso,hdc:cdrom,r']
boot='dc'
builder="hvm"
device_model="qemu-dm"
kernel="hvmloader"
vnc=1
vnclisten="0.0.0.0"
acpi=1
apic=1
serial = "pty"



Anyone have any explanation why XP would be going berserk?
