I have configured a dedicated migration interface in 3 node cluster and added that network in migration setting under datacenter. I can migrate/move VMs between node 2 & 3 successfully. But can't migrate VMS from node1 to node2 & node3. All the nodes are on same version 9.1.4. Cluster status is ok. I can SSH to node 1 from node 2 & node 3 console.
Ran the following on all the 3 nodes:
cd /root/.ssh
mv id_rsa id_rsa.old
mv id_rsa.pub id_rsa.pub.old
mv config config.old
pvecm updatecerts
While doing SSH to node 2 from node 2 &3, selected yes
The authenticity of host can't be established.
ED25519 key fingerprint is SHA256:bQ+oxk9G/FljDgwiDFpjxDuJox6dAlsVYcL6N8tzUbs.
This key is not known by any other names.
Are you sure you want to continue connecting (yes/no/[fingerprint])? Yes
I'm not sure, what else I'm missing?
