Description of problem:
i have fully virutalized guest with 2 NIC's eth0 is working but eth1 is
receiving packets not transmitting data and functional due to facing shares
both an interrupt and memory access address with usb device

Version-Release number of selected component (if applicable):0.12.5-1


How reproducible:


Steps to Reproduce:

1. Run VM with two NIC's support
2. On Child up both eth0 and eth1 
3. eth1 not working , interrupts detail mention in Additional info


Actual results:
eth1 is just receiving data not transmitting data

Expected results:
eth1 should be work


Additional info:

cat /proc/interrupts
            CPU0
   0:        219   IO-APIC-edge      timer
   1:          6   IO-APIC-edge      i8042
   4:         88   IO-APIC-edge      serial
   8:          1   IO-APIC-edge      rtc0
   9:          0   IO-APIC-fasteoi   acpi
  10:   32173856   IO-APIC-fasteoi   eth0
  11:     331891   IO-APIC-fasteoi   uhci_hcd:usb1, eth1

As see in 11: eth1 shares interrupts with usb device.

Both eth0 and eth1 using same NIC model as see below

cat /etc/udev/rules.d/70-persistent-net.rules

Please suggest, how we will functional eth1 ?
