Ah, qemudShutdownVMDaemon() is passed a NULL connection and then qemuCheckPciHostDevice de-references the NULL pointer.
I have a bunch of patches to re-work all this code which I will post later. Hopefully they will work better for you.
Thanks, Mark.
Hi,
i tried your patches and now it works, no segfault anymore.
Thanks for testing.
But the other problem is, that i tried a lot of pci device and passed them through in the guest, but none of them were usable in the guest.
I tried three WLAN-PCI-cards, installed the driver in the guest, but i had no success to get a signal from my WLAN-router. In the host, the cards works well, with same driver and same kernel.
The same problem do i have with my dvb-cards, in the host they works very well, i can create a channels.conf with scanning the transponders, but in the guest, i dont get any signal.
I think, its more a problem of qemu then libvirt.
Does your machine have Intel VT-d support and your kernel have it enabled? (e.g. dmesg | grep DMAR) If so, it's probably best to supply details to the qemu-kvm mailing list with lspci -vvv etc. Cheers, Mark.
