Unable to import VMs from VMware ESXi

[Claus G.]

Hi everyone,
we have a fresh installed PVE 8.2.3 3-node cluster with Ceph file storage backend. We are able to create/install/run new VMs, but migration of Windows Server 2022 VMs from our ESXi 8.0.3 cluster using the migration wizard and following the guide in this video https://www.youtube.com/watch?v=8Z9Zvt2RxlA fails with the following error:

Sep 09 12:30:43 pmx1 pvedaemon[2975182]: unable to create VM 108 - cannot import from 'ESXi-SRV2:ha-datacenter/SAN2RAID6Vol2/xxx.xxx.de/xxx.xxx.de-000001.vmdk' - qemu-img:

We tried several machines, all with the same error message. Adding ESXi as storage worked without any problems and all VMs are visible in import GUI.

Using Google did not help finding similar issues :-(

Any help highly appreciated!

Thanks,
Claus

OK, finally we found the solution: The VM to import must not have any snapshots. Otherwise the import will fail!

Hi, if necessary, you can try using the free version of Vinchin Backup & Recovery to migrate the virtual machine. I hope it can help you. I hope to receive more feedback on this product. Thanks a lot!
