Compared to the earlier version you posted as patch 6/5 on the pci
patches, you changed to a stack allocation of the bitmaps.

That's too small. If VIR_DOMAIN_CONTROLLER_TYPE_LAST is 8, it only sets
2 entries and leaves the last 6 uninitialized. You want:
memset(max_idx, -1, sizeof(max_idx));
ACK with the fixed initialization.
