[ovirt-users] import vm from iscsi storage domain fails with "Cannot import VM. Invalid time zone for given OS type. Attribute: vm.vmStatic"

Dear ovirt users, we are running RHV 4.4.8.6-0.1.el8ev on the manager and Red Hat Virtualization Host 4.4.6 (el8.4) on the hypervisors. Normally I would open a case at Red Hat but our subscriptions expired. We are currently in the process of purchasing new ones but this problem is really urgent so I thought I'd give it a try here. Sorry for that if its misplaced. We have a problem importing some VMs from a iscsi storage domain. We had an outage of the iscsi san volume but managed to recover the data and bring them back online. We imported the volume into a new data center and were able to import most of the vms which were on that volume. But now there are still some importand ones left and we do get the upper mentioned error. I searched the web and found a solution which proposes to alter the "operating system type" in the import dialog and change it to "linux". Oh, while writing "linux" I forgot to mention all of the problematic vms are windows ones. But the import dialog doesn't let me change the operation system type. I can only change the name. I found another solution here in the archive of this mailing list. Its pretty new I think. Topic was "How to re-import a VM with an invalid timezone?" in August. The solution was to add the missing timezone in a file (https://github.com/oVirt/ovirt-engine/blob/master/packaging/conf/timezone...) on the manager and restart ovirt-engine. I would love to try that but I really don't know what to put there. I can't open an ova file because the vm is on the iscsi domain in some lvs or metadata or .. I don't know where RHV reads that from. Hope I am not missing some important info. Any help would be greatly appreciated Cheers Timo
