Status in QEMU: New Bug description: Environment: ------------ Host OS (ia32/ia32e/IA64):ia32e Guest OS (ia32/ia32e/IA64):ia32e Guest OS Type (Linux/Windows): Linux(RHEL6u1) kvm.git Commit:186195928e8149b27cdd603a660dace454969f2b qemu-kvm Commit: 81bdec908fb2be0ccaff1d4ee67956c509e440ad Host Kernel Version:3.3.0-rc5 Hardware: Romley-EP, WSM-EP 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 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/953754/+subscriptions
