<p dir="ltr">I've recently started looking at oVirt to provide the next iteration of our virtualization infrastructure, as we have recently acquired some ISCSI storage. Up to now, we've been using KVM managed by libvirt/virt-manager locally on each of our hosts, using direct attached storage, which was obviously less than ideal.</p>
<p dir="ltr">In setting it all up, I've hit a bit of a snag. We've got 4 GbE network interfaces on our pilot host (running vdsm on CentOS 6.4) which are connected to our storage arrays (equallogic). I've created 4 interfaces with iscsiadm for these and bound them, but when setting up the discs in oVirt, I've not seen a way of telling it which interfaces to use. The node makes the connection to the target successfully, but it seems its only connecting via the "default" iscsi interface, and not making a connection via each interface that I've defined. Obviously this means I can't use multipath, and being only GbE interfaces it means I'm not getting the performance I should.</p>
<p dir="ltr">I've done some searching via Google, but I've not really found any thing that helps. Perhaps I've missed something, but can anyone give me any pointers for getting this to work across multiple interfaces?</p>
<p dir="ltr">Thanks?</p><span class="HOEnZb"><font color="#888888">
