<p dir="ltr">What do you mean by "having direct lun working" ? You already can, you need to add to the first line of multipath.conf a comment to make it private (don't remember the exact content) then you can set your luns in every host as desired. The bad thing is that you'll have to replicate the file to every host everytime you make changes. I did open an RFE in the past about this... I don't remember for sure as I'm not active to ovirt since a long time now.<br>

Hi,<br>
<br>
the "solution" to your problem<br>
is, that you don't need to setup<br>
any "on top" networking at all, after basic<br>
setup, so: no bonds, no vlans.<br>
<br>
Just configure everything in ovirt, you<br>
can easily construct some bonded setup<br>
with v-lans on top, ovirt creates it all for you.<br>
<br>

While I have never tested or used this feature myself, I'm pretty<br>
sure this is not normal behaviour, this shouldn't take that long<br>
on an idle vm, unless something else puts your hardware under heavy<br>
load?<br>

Well, what you can do, is:<br>
export this vm to an export domain, detach the domain from your DC,<br>
<br>
than tar.gz the whole export domain (use the sparse option if you got<br>
thin provisioned disks)<br>
then upload that tar.gz they have to put it on their storage, extract<br>
and import the export storage domain, then import the vm.<br>
<br>

PS: But I can't believe the redhat support is so bad, after all the<br>
"ovirt support" is pretty good.<br>

Just add "exclude=qemu-kvm*" in /etc/yum.conf so yum will leave them allone<br>

Is there any chance of multipath working with direct LUN instead of just<br>
storage domains ? I've asked/checked a couple of times, but not had much<br>
luck.<br>
<br>
Thanks<br>

Hi,<br>
<br>
the best way to get features into ovirt is to create a "Bug"<br>
titled as "RFE" (request for enhancement) here:<br>
<br>
<a href="https://bugzilla.redhat.com/enter_bug.cgi?product=oVirt" target="_blank">https://bugzilla.redhat.com/enter_bug.cgi?product=oVirt</a><br>
<br>
if you have any custom vdsm code it would be cool to share<br>
it with the community, so you might even not be responsible<br>
for maintaining it in the future, but that's your decision<br>
to make.<br>
