You should keep the users list cc'ed so everybody with the same questions can find the answers too :) Well I never have seen "lost" vms in ovirt, but if you want to move vms between storage domains afaik the only way to currently do so is to export a vm from a data domain to an export domain and than import from this export domain to another data domain. export domains are basically nfs storage systems, so you want to make sure your firewall and selinux settings are correct. it's also possible to detach export domains, tar them and then untar them in another ovirt einvironment and import this whole export domain (use the "-S" flag if you have "sparse" vms!). this should also be possible for data domains somehow: http://www.ovirt.org/Features/ImportStorageDomain but I didn't try this myself yet, so I don't know if this really works yet (new features tend to need a point release until they are matured enough ;) ) HTH -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

In the same DC all you need to do is "right click" and select "move", can be done live.

Yep, note that it's a little different from VMWare in that it takes a snapshot for each disk in the VM to do a live storage migration, and the snapshots can't be deleted while the VM is powered up (in 3.4 at least). You can also only move 1 disk at a time per VM if it's powered up. -----Original Message----- From: users-bounces@ovirt.org [mailto:users-bounces@ovirt.org] On Behalf Of Sven Kieske Sent: October-24-14 9:19 AM To: Dan Yasny Cc: Users@ovirt.org List Subject: Re: [ovirt-users] vmware type functionality On 24/10/14 16:39, Dan Yasny wrote:

Storage Domains that belong in the same DC. This is the only reason for the "move" feature to exist - move VM disks between SDs

Is it correct to say that this is possible only if both SDs are file based ones or if both are block based ones? Or was this limitation overcome in 3.5? Gianluca

export domains are basically nfs storage systems, so you want to make sure your firewall and selinux settings are correct.
it's also possible to detach export domains, tar them and then untar them in another ovirt einvironment and import this whole export domain (use the "-S" flag if you have "sparse" vms!).
this should also be possible for data domains somehow:
http://www.ovirt.org/Features/ImportStorageDomain
but I didn't try this myself yet, so I don't know if this really works yet (new features tend to need a point release until they are matured enough ;) )
HTH
3.5 adds ability to see VMs on the domain not in the engine and add them (part of import domain). not intended for "lost vm's", except maybe after recovery of engine from old backup. or for vms injected to data store by various tools
