[libvirt] [PATCHv2 00/12] remains of 'support VFIO groups'

This is what remains of yesterday's VFIO groups patchset that is considered still useful, but wasn't yet ACKed (I've pushed the 5 that were ACKed). In addition, I found a few more bugs in the virPCIDeviceList handling and have included patches for those. There are a couple of these that would be really nice to get into 1.0.7, one in particular which is new functionality, but has 4 prerequisites: The most important patch here from a functionality point of view is PATCH 05/12, which adds the <iommuGroup> element to the output of "virsh nodedev-dumpxml". This is essential for users/management applications to have adequate information to know which devices need to be detached from host drivers. (Unfortunately, all of the patches prior to 05/12 are required for 05/12 to cleanly apply.) The other new patch that I've been told is important is 08/12, which supresses reset of PCI devices that were/will be assigned using VFIO - apparently the vfio driver already resets the devices when appropriate, so having libvirt do it is just redundant. (In order for 08/12 to operate reliably, 07/12 is required, and in order for 07/12 to apply, 06/12 must also be applied). If someone ACKs any of these patches prior to DV cutting the first rc and I don't respond on IRC (not sure what my schedule is in the next 12 hours :-), please feel free to push any of them you like, as long as you push them in order with none missing from the middle.
