Import VM via KVM. Can't see vm's.

Hi I am trying to migrate vm's from oVirt 4.3.10.4-1.el7 to oVirt 4.5.3.2-1.el8. I use Provider KVM (via libvirt) My problem is that I can't see vm's from old oVirt when they are shutdown. When they are running I see but can't import because "All chosen VMs are running in the external system and therefore have been filtered. Please see log for details." Thank you for help. Regards

Yep, that's expected since oVirt defines transient guest domains. The KVM provider is rather intended for persistent guest domains that are not managed by oVirt. See [1] for more details about those. The preferred way to migrate VMs from one oVirt deployment to another is by using OVAs (export from the source and import to the destination, possibly using shared storage) Another way to achieve this is by detaching a storage domain that the VMs reside in from the source, attaching it to the destination and import the VMs from that storage domain. And there's a third option - to use the deprecated export domains, which is not tested anymore but could work. [1] https://wiki.libvirt.org/page/VM_lifecycle#Transient_guest_domains_vs_Persis...
