[ovirt-users] VM Network Interfaces - bad cluster network and VLAN assignment

[J. Mikulec]

Ahoj :)

After huge testing today :) I see it is problem just if I add NICs after 
VM creation and automatically assigned MACs are 00:1a:4a:c4:e4:11 and 
00:1a:4a:c4:e4:ef. In this case there is also desc alphabetical sorting 
of nic (sorting by MAC?).

This problem is NOT when:

- NICs are added in time of VM creation (windows New Virtual Machine, 
tab General)
- 1 NIC is added in time of VM creation and 1 added later
- when all NICs are added later and oVirt assign another MAC
