Bug Description
qemu-kvm Commit:
NIC doesn't work with "pci=nomsi" in grub.conf. Neither static assignment nor hot-plug assignment works.
And when using qemu-kvm's commit 08bb9f6b1a5d8f4
Reproduce steps:
1.build and install qemu-kvm
2.plug off a NIC device from host (BDF of NIC: 13:00.0)
3.start a guest (grub.conf has a configuration "pci=nomsi") :
qemu-
4.[Guest] dhclient
The NIC assigned before cannot get an IP address. It doesn't work.
