VM Network Interfaces - bad cluster network and VLAN assignment
Hello, I have 4 Cluster networks and I am trying to add 2 NICs to VM now: nic0 -> br0 nic1 -> br1 At ovirt-engine it seems ok, but assignment in qemu is incorrect - going to this: nic0 -> br1 nic1 -> br0 So nics belongs to incorrect bridges and so incorrect VLANs. It does oVirt totally unusable for me (we strictly use 0 network for public IPs and 1 for intranet use) :( With one NIC I not see this problem. http://tinypic.com/view.php?pic=29pzxbr&s=8#.VBjLUxYoEiw http://tinypic.com/view.php?pic=2hdd07m&s=8#.VBjLgRYoEiw Thank for help.

Ahoj Jiří, Are you sure that the networks are indeed wrong, for example that guest's NIC with ...:11 MAC is plugged to br0 network and ...:ef NIC is plugged to br1 network? If so that would be a serious bug. I thing however that you just see guest OS NIC naming race conditions, maybe if ovirt's NIC names would be prefixed with nic- instead of eth- by default, such confusions wouldn't happen... For some reference, bug [1] is implemented consistent NIC order in the portal and [2] to be able to modify pci addresses as well (as they are used by some OSs to base NIC naming on).

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 J.
