IIRC, this was a problem with older versions of QEmu that was fixed later. Are you on a recent version? You should be able to run a single VCPU, Windows XP instance *without* ACPI and have low CPU usage. I've done it. Note, this problem still exists for multi-VCPU XP instances. .:. jeremy On Mon,

For me it eats 10-20%, and I was not able to lower that (linux uses 0%). And if I am not mistaken, it eats 100% when you have chosen wrong ACPI parameters in domain.xml. Take a look at https://bugs.launchpad.net/ubuntu/+source/virt-manager/+bug/228442 On Tue, Jan 11, 2011 at 00:25, Matthias Meyer

When my Windows 2003 guest is idling (0% vcpu usage), host os is idling too ( up to 3% cpu). Did you check the guest os and find out the process which is eating your cpu time? On Mon, Jan 10, 2011 at 2:05 AM, Matthias Meyer wrote: > Hello, > > I run Debian on my Laptop Lenovo X60s (with VT).

[libvirt-users] Windows guest eats as many CPU as available

Hello, I run Debian on my Laptop Lenovo X60s (with VT). I've created a Windows-XP as well as a Windows-Vista guest on it. Both, XP as well as Vista, eats as many CPU as available. Therefore the CPU always has high load and will never reduce cpu-frequenz or ventilator. Did this works as designed
