</span>Hello,<br>
<br>
just on the status of the feature (as it's exactly what you require - direct<br>
pci device attachment) - the host side is hopefully ~week away from being<br>
ready, the UI side will take longer though - if you wanted, you could probably<br>
run nightly and spawn the VM yourself and treat is as external VM. CCing Martin<br>
Betak, who is the one to blame for the UI :)<br>
<br>
You also need RHEL 7 (ideal support will be in 7.1) and I suggest reading<br>
the chapter on IOMMU groups, as you might need to block (detach from host)<br>
other devices than the nic in order to get it passed through.<br>
