Creating a iSCSI bond is indeed the recommended way to use iSCSI multipathing with oVirt http://www.ovirt.org/Feature/iSCSI-Multipath#iSCSI_Bond_behaviour But it relies on oVirt logical network that are still not available when you are deploying hosted-engine and with oVirt 3.5 you cannot than edit the hosted-engine storage domain. A manually configured bond should work but than is not directly managed by the engine for additional hosts. > - If I'll use a bond, will it survive the engine's installation? hosted-engine is generally working with bonded interface and they generally survive but honestly I never directly tried deploying hosted-engine on iSCSI over bonded interface. Please report us if you find any issue with that. > - After the engine's installation, the link(s)/path(s) used to connect to > the SAN storage will also be used to connect to the NAS, this will > constitute a storage network, this network will be mandatory so I can't > create an iSCSI bond on top of it.

I think no, currently you cannot edit the hosted engine storage domain from the engine to configure the iSCSI bond involving another logical network. We are working on that for 3.6 > thanks in advance. > > 2015-03-24 10:30 GMT+01:00 Simone Tiraboschi <stira...@redhat.com>: > > > > > > > ----- Original Message ----- > > > From: "Baptiste Agasse" <baptiste.aga...@lyra-network.com> > > > To: "users" <users@ovirt.org> > > > Sent: Tuesday, March 24, 2015 10:12:36 AM > > > Subject: [ovirt-users] Hosted engine multipath iscsi > > > > > > Hi all, > > > > > > I'm currently testing ovirt 3.5 on centos 7, with hosted engine on iscsi > > > equallogic SAN..
