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.
