Hi,
i want to use more then one pci card in my debian guest.
But when i start the guest, the log says:
libvirtd: 15:44:55.459: warning : pciTrySecondaryBusReset:483 : Other devices on bus with 0000:05:01.0, not doing bus reset
With "/usr/bin/qemu-system-x86_64 -m 512 -name test -hda /media/vm/test.img -boot c -vnc :2 -k de -pcidevice host=05:01.0 -pcidevice host=05:02.0 -pcidevice host=05:03.0" there seems to be no problems.
I'm afraid this is purely a limitation with the current code in qemu: /* For now, we just refuse to do a secondary bus reset * if there are other devices/functions behind the bus. * In future, we could allow it so long as those devices * are not in use by the host or other guests. */ if (pciBusContainsOtherDevices(conn, dev)) { VIR_WARN("Other devices on bus with %s, not doing bus reset", dev->name); return -1; } We also have a bug tracking this issue: https://bugzilla.redhat.com/499678 Fixes welcome! :-) Cheers, Mark.
