[Bug 618916] [NEW] attach-interface only works every other time

[Jamie Strandboge]

Public bug reported:

After starting a VM, attach-interface does not work the first time, but
does the second. Notice the following set of commands:

$ virsh -c qemu:///system attach-interface "qatest-i386" network default --mac "52:00:00:00:00:00"
error: Failed to attach interface
error: operation failed: adding rtl8139,vlan=1,id=net1,mac=52:00:00:00:00:00,bus=pci.0,addr=0x5 device failed: pci_add_option_rom: failed to find romfile "pxe-rtl8139.bin"
$ virsh dumpxml qatest-i386 | grep 52:00
$ virsh -c qemu:///system attach-interface "qatest-i386" network default --mac "52:00:00:00:00:00"
Interface attached successfully
$ virsh dumpxml qatest-i386 |grep 52:00
      <mac address='52:00:00:00:00:00'/>
$ virsh -c qemu:///system attach-interface "qatest-i386" network default --mac "52:00:00:00:00:00"
error: Failed to attach interface
error: operation failed: adding rtl8139,vlan=2,id=net2,mac=52:00:00:00:00:00,bus=pci.0,addr=0x7 device failed: pci_add_option_rom: failed to find romfile "pxe-rtl8139.bin"
$ virsh dumpxml qatest-i386 |grep 52:00
      <mac address='52:00:00:00:00:00'/>
$ virsh -c qemu:///system attach-interface "qatest-i386" network default --mac "52:00:00:00:00:00"
Interface attached successfully
$ virsh dumpxml qatest-i386 |grep 52:00
      <mac address='52:00:00:00:00:00'/>
      <mac address='52:00:00:00:00:00'/>

I have the kvm-pxe package installed and "pxe-rtl8139.bin" is available,
so I don't know why qemu is complaining. This is not an AppArmor problem
(it would block every time). This was found by using the test-libvirt.py
script in lp:qa-regression-testing.
