[ovirt-users] Re: Can't import some VMs after storage domain detach and reattach to new datacenter.

Hi Nir, Trying to revive this old thread, I ran in to a similar issue. I imported a few VMs from an old VMWARE version into ovirt 4.3.3 using OVAs generated on the VMWARE side. After adjusting a bit the OVAs I was able to do the import. A year later I have tried to export those VMs from 4.3.3 to a new Hyperconverged cluster that uses oVirt 4.3.10. If I try to import a VM with only 1 disk I need to modify the DISKTYPE from 1 to DATA, and Need to add the alias on the DESCRIPTION field as it does not appear on the v5 (ovirt 4.3.10).

So I had to create the VM and attach the imported disk and worked fine. Then I tranfered the disk from the NFS domain to the VMSTORE Gluster domain... up to here all good. Problem when I tried to do the same with a VM with 2 disks, up to starting the VM all was good, however migrating the storage to the VMSTORE Gluster domain the second disk stays in migration forever, issue related to deleting auto generated snapshot of the second disk. In order to half way solve the issue I had to follow up on: https://access.redhat.com/solutions/396753 https://access.redhat.com/solutions/1347513 https://access.redhat.com/solutions/3991591 /usr/share/ovirt-engine/setup/dbutils/ https://lists.ovirt.org/pipermail/users/2016-May/039898.html but this caused a lot of downtime, so right now 1 disk of the VM is on VMSTORE DOMAIN (Gluster), and one disk on the migration data domain (NFS). Seems I can't transfer the second disk to VMSTORE Domain. Any ideas? Thanks, AQ
