| Thread-topic: | [PATCH] disallow duplicate pci device strings in guest config file |
When we specify duplicate pci device strings in guest config file, like pci=['01:00.0', '01:00.0'], or pci=['01:00.0', '0000:01:00.0'], or pci=['01:00.0', '0000:01:00.0@7'], xend doesn't detect this case and passes the pci string to ioemu and ioemu invokes register_real_device() twice for the same physical device and this could cause unexpected behavior. The patch detects this case and makes the domain construction fail. Signed-off-by: Dexuan Cui <dexuan.cui@xxxxxxxxx>
