[libvirt-users] TUNGETIFF ioctl() failed - virtual machine can't start

[Matthias Meyer]

Hi,

I want to migrate from vmware to KVM. Therefore I have installed debian 
stable (lenny) and create two virtual machines (KVM).
Both (XP as well as Vista) running fine.
After upgrading to debian testing (sqeeze) both XP-guest as well as 
Vista-guest didn't start anymore.
Both are failing during preparation, probably because of a network-problem.
I will give XP as an example:

cat /var/log/libvirt/qemu/devel-xp.log.2
/usr/bin/kvm -S -M pc -m 256 -smp 1 -name devel-xp -monitor 
pty -localtime -no-acpi -boot c -drive 
file=/KVM-Images/devel-xp.qcow2,if=ide,index=0,boot=on -drive 
file=/mnt/MultiMedia/CD-Server/Betriebssysteme/Windows/WindowsNT/WindowsXPpro_sp2_de.iso,if=ide,media=cdrom,index=2 -net 
nic,macaddr=54:52:00:29:1a:2d,vlan=0 -net 
tap,fd=11,script=,vlan=0,ifname=vnet0 -serial pty -parallel 
none -usb -usbdevice tablet -vnc 127.0.0.1:0 -k de
char device redirected to /dev/pts/1
char device redirected to /dev/pts/2
info cpus
-> the above will run fine before the upgrade

the following will fail after the upgrade
tail /var/log/messages:
