Bug detailed description:
--------------------------
SMP guest cannot get two IP addresses when assign two NICs with igb driver.
I tried with Intel I350 and 82576 Ethernet Adapter.
Note:
1. when assign two NICs, both of the drivers are igb, the guest get only
get one IP.
2. When assign two NICs, one driver is igb, another is ixgbe, the guest
can get two IP address.
3. UP guest can get two IP.
4. smp guest, and assign two VFs with igb driver, the guest can get two IP
addresses.
This should be a qemu-kvm bug.
kvm + qemu-kvm = result
18619592 + 81bdec90 = bad
18619592 + b5ed4b6f = good
Reproduce steps:
----------------
1. start up a host with kvm kernel
2. /root/pcistub.sh –h 08:00.0
3. /root/pcistub.sh –h 0d:00.1
4. qemu-system-x86_64 –m 512 –smp 2 –device pci-assign,host=0d:00.1
–net none –device pci-assign,host=08:00.0 –net none –hda
/root/rhel6u1.img
5. ifconfig
Current result:
----------------
Only one can work
Expected result:
----------------
Both NICs can work
