Re: [libvirt] [PATCH 00/13] PCIe fixes + new PCI controllers w/RFC

To be honest, I kinds dislike all of them. Not that they would be chosen poorly, no, it's simply because the good sensible choice is unavailable due to another poor decision in the past (this may be another point for Michal's talk on KVM Forum). Thinking about it I must say I don't like how target (which is supposed to match a place where the device appears for the guest) is used for the model specification, on the other hand (ab)using 'model' element for the specification of an "address" in guest (that's what I understand chassis and port are) doesn't feel any better. What if we go with two of those elements? Would that be too much pain? E.g.: <controller type='pci model='pci-root-port' index='3'> <address type='pci' bus='0' slot='4' function='1'> <model type='ioh3420'/> <target chassis='3' port='0x21'/> </controller> I understand this might look like an overkill, but I think it's better safe then sorry, I guess I just see us not so far in the future regretting any decision made now.
