Hi,
On my own build linux system without systemd, I have following problem,
when I try to start a qemu VM, libvirtd.log says:
2015-06-23 08:29:25.498+0000: 889: error : virNetDevGetIndex:842 : Unable
to get index for interface vm0.0: No such device
2015-06-23 08:29:25.551+0000: 886: error : virNetDevGetIndex:842 : Unable
to get index for interface vm0.0: No such device
2015-06-23 08:29:25.611+0000: 888: error : virNetDevGetIndex:842 : Unable

...
virsh dumpxml vm:
...
<interface type='ethernet'>
<mac address='52:54:00:cd:15:51'/>
<target dev='vm0.0'/>
<model type='virtio'/>
<boot order='3'/>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x0f'
function='0x0'/>
</interface>
...
I had no problems with 1.2.12, so I started a git bisect and I came down
to this:
# first bad commit: [4bbe1029f2fb6cd1c102794951a944c62fdbd0e6] qemu: fix
ifindex array reported to systemd
When I revert that commit on top of 1.2.13.1, problem is gone.
I tried today's version (d10a5f58c75), problem is still in there.
Hope this is useful to you?
