Hi, thanks for you improvements. I updated libvirt with git and tried to passthrough two pci devices to a linux guest. <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x0000' bus='0x05' slot='0x01' function='0x0'/> </source> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x0000' bus='0x05' slot='0x03' function='0x0'/> </source> </hostdev> In the guest, only one of them works and after the shutdown of the guest, i got a segfault on the host. libvirtd[15363]: segfault at 38 ip 0000000000421164 sp 00007fff59d1dfb0 error 4 in libvirtd[400000+6d000] I use kernel 2.6.30-4 on the host. What did i wrong? Greetings
Hi, Here's a fairly mixed set of KVM PCI device assignment improvements:
- Add hotplug support
- Allow PM reset on multi-function devices
- Allow Secondary Bus Reset even if it causes other devices to be reset, so long as those other devices are in use by the same VM or are unused
- Re-attach devices when the guest shuts down
- Properly detect versions of QEMU without -pcidevice support
Cheers, Mark.
