iSCSI to a DELL PS Series Storage array... no bonding in their minds.... ;-(

I would try and see...
At this moment I only have ovirtmgmt configured on other 2 network adapters.

[root at ov300 ~]# brctl show
bridge name bridge id STP enabled interfaces
;vdsmdummy; 8000.000000000000 no
ovirtmgmt 8000.1803730ba369 no bond0.167

and
[root at ov300 ~]# cat /proc/net/bonding/bond0 | grep "Interface:"
Slave Interface: em1
Slave Interface: em2
[root at ov300 ~]#

And iscsi configured on p1p1 and p1p2 on vlan 100

[root at ov300 ~]# ifconfig p1p1.100
p1p1.100: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 9000

I will see as soon as I will try to add an oVirt network using p1p1 and p1p2
