Hello,
I have been trying (unsuccessfully) to add my Infiniband HCAs on my VM hosts to oVirt
4.0.4. I am not using IBoIP, just plain Infiniband. I would like to be able to pass
through the card (or better yet the VF from SR-IOV) to the guest VM.
SR-IOV should work (or general PCI passthrough), it’s then transparent to oVirt. Did you
not succeed with setting up SR-IOV or generic passthrough of the HCA?
From what I can figure out, oVirt is trying to bridge the interface but I don't think
that will work as shown here [1]. Does oVirt currently have support for passing through
Infiniband to VMs? If not, are there any plans to support it?
Well, at least for generic passthrough the PCI device would be detached from the host so
should not be recognized/touched by oVirt networking code at all.
Thanks,
