[libvirt-users] PCI-Passthrough suddenly stopped working

Hi everybody! On a Centos 5.8 with libvirt qemu-0.10.5-1.el5.2, libvirt-0.8.2-22.el5 and 2.6.18-308.11.1.el5 I have a Windows machine that used to have pci-passthrough for a device enabled and working. After an update (kernel, libvirt afaik) and a reboot, pci-passthrough stopped working. Intel IOMMU is enabled (can see that from the dmesg output). All i get on the console when i try to start the vm is the following: Fehler: internal error process exited while connecting to monitor: char device redirected to /dev/pts/3 Failed to assign device "14:00.2" : Invalid argument Failed to deassign device "14:00.2" : Invalid argument Failed to initialize assigned device host=14:00.2 SELinux ist disabled. Does anyone have any hint what could have possibly gone wrong? As an additional info: "virsh nodeddev-list" also doesn't work. I don't know if I mix that up, but i seem to remember that that used to work on that machine. root@kvm ~]# virsh nodedev-list --tree Fehler: Failed to count node devices Fehler: this function is not supported by the connection driver: virNodeNumOfDevices Any hints are greatly appreciated!
