<br>
I'm looking to add a new host to my oVirt lab installation.<br>
I'm going to share out some LVs from a separate box over iSCSI and will hook the new host up to that.<br>
I have 2 NICs on the storage host and 2 NICs on the new Ovirt host to dedicate to the iSCSI traffic.<br>
I also have 2 separate switches so I'm looking for redundancy here. Both iSCSI host and oVirt host plugged into both switches.<br>
<br>
If this was non-iSCSI traffic and without oVirt I would create bonded interfaces in active-backup mode and layer the VLANs on top of that.<br>
<br>
But for iSCSI traffic without oVirt involved I wouldn't bother with a bond and just use multipath.<br>

<br>
So what's the best/most-supported option for oVirt?<br>
Manually create active-backup bonds so oVirt just sees a single storage link between host and storage?<br>
Or leave them as separate interfaces on each side and use oVirt's multipath/bonding?<br>
<br>
Also I quite like the idea of using IPv6 for the iSCSI VLAN, purely down to the fact I could use link-local addressing and not have to worry about setting up static IPv4 addresses or DHCP. Is IPv6 iSCSI supported by oVirt?<br></blockquote><div><br></div><div>No, we do not.
