Title:
NIC doesn't work when it had been us
I found this problem, too. A VM used a NIC with PCI-passthrough mode.
Then I shutdown the VM, and tried to give the NIC back to the host. But
I found I couldn't assign the NIC to the host again. This problem
didn't occur each time. If I did this steps for ten times, I could see
it at least once.
Nevermind, reproduced on 2.6.38

Are you using libvirt to launch the guest or qemu command line? Please
provide xml/command line used. Are you able to reproduce this on a
stable kernel? The referenced kvm.git commit is 2.6.29-rc2+, which I'm
not even able to get to boot on my system. I can't reproduce the
problem using command
hot-plug NIC doesn't have this issue.
