Comment 4 for bug 1383465

Robert,
I have a couple to passthrough.`:
01:00.0 Ethernet controller [0200]: Broadcom Corporation NetXtreme BCM5720 Gigabit Ethernet PCIe [14e4:165f]
01:00.1 Ethernet controller [0200]: Broadcom Corporation NetXtreme BCM5720 Gigabit Ethernet PCIe [14e4:165f]

However, I passed an entire 10G nic, I was not using SRIOV.

The test rebooted the host, so you could simply reboot the host, or try stop openstack services and virsh destroy instance-000000XX to recreate

The machine I was testing on has something running on it as we speak. I was going to recreate to see if I can get more information for you.
