Re: [ovirt-users] Directly connect NIC or other cards to VM?

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

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
