I have installed (painfully - almost 6 hrs, though I have done the acpi tricks at cd boot) Windows XP SP2 as a kvm guest.
However, the network performance is terrible (~200 kbps with small bursts up to 2 Mbps). No matter what NIC type I use, either virtio or hypervisor default rtl8139, and from time to time I get a win32host error and ics (Windows firewall and internet connection sharing) service crashes, with no explanation in the logs (except access is denied) --> system is not stable.
This problem happened to an SP2 and a different SP3 installation, so I would assume it is a virtualization issue.
The host is Debian Squeeze (kernel upgraded to 2.6.38 from squeeze-backports - this helped a bit for the guest performance) and both kvm and libvirt are upgraded to the latest version from sid repositories. The physical machine is an HP G120 server.
I have read in several places that Windows XP can be run under kvm, but I would like to hear a "Windows XP under kvm" success story with performances near those of a VMWare 2/ESXi guest or any hints that could guide me in the right direction.
