can you verify the db from before the upgrade has the VMs?
I dont know what you mean by verify database. Please, could you point me how to do it? Thank you _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
I assume from your expectation to see the VMs from the previous install that you upgraded your system rather than do a clean install? in an upgrade, there should be a backup of the db from before the upgrade. (in a clean install, engine is not aware of VMs running on hosts from previous installs - we need to cover "import existing storage domain" in a future version to close this gap. current alternatives around this are to convert the storage domain to an export domain (for an nfs data domain) an re-import them to the system or a few other options.
how many VMs are there? They(VMs) are deleted. So, my situation is this:
I have clean install of ovirt 3.3.0beta with imported VMs from export domain. Everything works except snapshots. But when I restart ovirt mgmt server, VMs will disappear. Right now I am doing hourly backup of DB.
this is very fishy... can you arrange for a remote access session for someone to take a look?
I can not use workaround with converting domain to export domain, because we use iscsi. It would be perfect if I can retake existing domain. Another gap is if I dont detach export domain I can not attach it to new datacenter and I have to manually edit some files. It would be absolutely perfect to do it from ovirt web gui (for example by "force override button")
i thought 3.3 allowed for that, but i could be wrong.
Well, I will backup all VMs to export domain, than create snapshot of ovirt and I will try to restart that server if its going to delete VMs from DB. Than I will report back. I think, that remote session will not be possible, but I can be wrong (I hope).
remote session could be via a webex-like, giving control to remote person via the webex-like tool - not direct internet connection to the machine
