            Status: NEW
          Severity: high
          Priority: P1
         Component: kvm
        AssignedTo: virtualization_kvm@kernel-bugs.osdl.org
        ReportedBy: yongjie.ren@intel.com

kvm.git Commit:b48b2c3e50433ff6f7e46186daa7f986bd960215

Host Kernel Version:3.4.0
Hardware:WSM-EP, Romley-EP


Bug detailed description:
--------------------------
Assign a VF or normal NIC to the guest, the guest cannot get IP address.
Note:1. assign the VF of  Intel 82576 NIC or 82599 NIC, the guest cannot get IP
     2. hot plug a VF to the guest, the guest cannot get IP
     3. assign a PF to the guest, the guest cannot get IP.


kvm(next) + qemu-kvm   =  result
b48b2c3e + 18a188f6   =  bad 
322728e5 + 18a188f6   =  good



Reproduce steps:
----------------
1. ./pcistub.sh -h 08:10.0   ( to hide a device)
2. qemu-system-x86_64 -m 512 -device pci-assign,host=08:10.0 -net none -hda
rhel6u1.qcow

Current result:
----------------
The guest cannot get IP

Expected result:
----------------
The guest can get IP

Basic root-causing log:
