Hello there,

I'm following https://www.ovirt.org/develop/release-management/features/virt/KvmToOvirt/ guide in order to import VMS from Libvirt to oVirt using ssh.

URL: "qemu+ssh://host1.example.org/system"

and get the following error:

Failed to communicate with the external provider, see log for additional details.

oVirt agent log:

- Failed to retrieve VMs information from external server qemu+ssh://XXX.XXX.XXX.XXX/system

- VDSM XXX command GetVmsNamesFromExternalProviderVDS failed: Cannot recv data: Host key verification failed.: Connection reset by peer
