I've figured out how to map a specific network interface to a VM, thats one step, but in the end I may need direct access to the PCI device itself.
I think this 3.6 feature might do exactly what you want: http://www.ovirt.org/Features/hostdev_passthrough It's gonna be a while before 3.6 is out, but once the feature is merged it'll be available if you install the nightly snapshot. CCing Martin Polednik, the feature owner.
Second to that, for network interfaces mapped to a particular VM, is there a way for the VM to be able to properly detect physical link state of that interface? Right now that's a 'configurable option' inside network interface settings on the VM in the manager (ie, plugged, not plugged, and link state up /down)
If I'm not mistaken, once you have direct access to the PCI device you'll be able to query for its actual state using e.g. ethtool.
Thanks, David
