Hello all,
we've managed to find the vm definitions in one of the logical volumes.
"Europe/Berlin=Central European Standard Time" was missing. After adding that in
10-timezones.properties under /etc/ovirt-engine/timezones and doing a restart of the
engine, it was possible to import the vms.
I am so glad we could find and fix this. Thanks to all for your replies.
Cheers and have a nice day
Timo
