a migration issue

…

system: RHEL 6.3
vdsm: ovirt master head

Trying to migrate a VM, created from *CLI* , I've got two errors (at 
least) on the target host:

1. the network interface has no «network» attribute (libvirtvm.py:936)
2. the network interface has no «macAddr» attribute (libvirtvm.py:2972)

So, we have an issue

1. either in vdsClient
2. or with the migration algo
3. or with NetworkInterfaceDevice class

Right now I'm tracing what's wrong there, but if you have any ideas, it 
will be nice.

Are both source and target the same?
Would you provide the complete traceback, as well as the whole
migrationCreate command from the destination log?

Did you provide them on cmdline? They're marked as mandatory but iirc not
checked/enforced on VM creation using vdsClient

I do provide «macAddr», but do not provide «network»

so can you try with network as
well?

Somehow you have two interfaces defined, both with the same macAddr
00:00:00:00:00:01 and network rhevm. This does not help much in
understanding the validation problem that you found in vdsm, but it may
help you.
