Re: [ovirt-users] Migrate from one system to another.
Hello Itmar, thanks for sharing the Glance service idea - but one question: All the info I found only mentions importing from glace [1]. Can you point out how to export VM images to a glance repository from oVirt? Until now I was not able to find this... Thanks!

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

Re: [ovirt-users] Migrate from one system to another.
Hi Gianluca, When I said the support has not been stellar I may have understated the problem. The reason I haven't opened a case with Red Hat this time is simply because *all* my other cases are still unresolved, with all but the most recent having been open for months. I've had to find my own workarounds for each, so I'm disinclined to waste even more time trying to get them to help me. My confidence in their support is pretty close to zero at this time. Both ends of this set-up are RHEV 3.3, with neither side having admin access to the other. The connection is via a VPN with a ping time of 300ms. These are independent companies. We each make some shared resources available to the other, so the normal method we use to transfer files is we upload them to a shared directory at the other end. regards, John On 04/07/14 17:54, Gianluca Cecchi wrote: Even if not stellar (as you said), if you have (as I understood) RHEV on both sides, you could open a case for this problem to red hat if not already done.

Thanks Sven but what you linked to is a bug in a feature in a version we don't use yet.

Re: [ovirt-users] Migrate from one system to another.
Hi Joop, Yes, that is an option but it also seems like an extra step that shouldn't be required. While in this instance that may not appear to be a big deal, in the future it's quite possible that we may decide to migrate our entire system from RHEV to Ovirt. Having to use additional steps for every VM to be migrated would result in far more downtime than we would be able to accommodate. Incidentally, I know of similar products but did not know about fsarchiver. I'll check that out, thanks. regard, John On 03/07/14 05:29, Joop wrote: On 2-7-2014 3:23, John Gardeniers wrote: Hi All, We need get get a VM from our client's system in the UK to our system in Australia, so this isn't just migrating between clusters or datacenters.
