Hi<br>
<br>
I'm using InfiniBand to make shared storage. My setup is simple: the
opennebula installdir is shared on NFS with the worker nodes. <br>
<br>
- I don't understand what you mean on shared image. There will be a
copy (or symlink if the image is persistent) on the NFS host and
that is that the hypervisor will use over the network. Live migrate
is available beacuse you don't move the image only another host will
use it from the same spot. With my linux images I have about 30s
delay when livemigrate. You can use qcow2 driver for shared image.<br>
<br>
- I don't understant exactly what you mean on "guest unaware". If
you mean storage - host connection it has nothing to do with nebula.
You can use any shared filesystem. NFS uses IPoIB connection.<br>

<br>
I'm interested in hearing user accounts about using infiniband as
the storage interconnect with OpenNebula if anyone has any
thoughts to share. Specifically about:<br>
* using a shared image and live migrating it (e.g. no copying of
images).<br>
* is the guest unaware of the infiniband or is it running IB
drivers?<br>
* does the host expose the volumes to the guest, or does the guest
connect directly?<br>
* I'd like to avoid iSCSI over IPoIB if possible.<br>
* clustering filesystem/LVM requirements.<br>
* file-based vdisk or logical volume usage?<br>
<br>
Anything, an experiences at all will be helpful.<br>
<br>
Thanks<br>
Christopher<br>
