vCenter :: Restore VM

[mcabrerizo (Miguel Ángel Alvarez Cabrerizo)]

Hi Carlos,
I have no previous experience dealing with Zombies VM, which I think are defined as VMs that were launched with OpenNebula but, for whatever reason, OpenNebula is not aware of this, e.g having different OpenNebula installations…

As another Carlos explains here:

Zombie recovery

Hi, We don’t have a procedure for this specific use case. Zombie VMs are meant to be a warning of a VMs that need manual clean-up, not to be re-imported. Ideally, you should create a new VM from scratch. Having said that, you could try 2 things to recover that old VM: Change the vm name in the hypervisor to anything other than ‘one-*’. This way, OpenNebula will detect it as a wild VM instead of a zombie VM. A wild VM can be imported, but it will have limited support. The images and vnets …

…if the problematic VM was called one-* you may change its name in vCenter and try to reimport it but I think it’s not the case. As it’s not using the default one- prefix, was the Ubuntu1404 VM a wild VM imported to OpenNebula?

I’m just guessing… if it was an imported VM maybe there’s an entry in the database refering to that Ubuntu VM and that prevents it to be reimported and that’s why it’s shown in the Zombies Tab.

According to docs imported VMs have limitations (can’t be recovered, recreated, undeployed, migrated, stopped…) so perhaps that’s the way it should be and the backup method you proposed is not suitable for this kind of VMs… hope some user can provide its experience in backup and restoring.

Cheers!
