Hi Nathanaël,

Yeah, I think I'll have to just use a physical NIC for the ovirtmgmt.
Too bad, it would be nice to be able to separate it from the standard
network.

Actually in several environments I can use globally only 4 network adapters, but they are all 10Gb/s.

So in this case is a shame to use a pair of them for ovirtmgmt only...

I use 2 of them in bonding (802.3ad) for ovirtmgmt and VMs, and 2 of them for iSCSI, migration network and NFS access

The culprit is to pre-define the bond on the host and set ovrtmgmt as a vlan based network with the vlan id that is necessary in your case.

Eg on one environment of these my vlan for ovirtmgmt is 68

In this case on the host there will be bond0 before setup and then after setup they will be created bond0.68, bond0.65 interfaces and ovirtmgmt bridge and vlan65 bridge

8: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000

24: bond0.65@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master vlan65 state UP group default qlen 1000

25: vlan65: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000

In another environment I have 4 interfaces and ovirtmgmt not set up as vlan based, but I can configure the switch ports as trunk with vlan 187 enabled and as default vlan set the 68 one, so that if packets are not tagged they go through that vlan.

In this case on one host I have to preconfigure the bond0 and then at the end of setup I will have something like this:

45: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue master ovirtmgmt state UP group default qlen 1000
