Hy.
I'm testing Proxmox Cluster with 3 Servers and a VM.
I'm Using a shared Iscsi storage with Lvm.
I can migrate the VM in live mode to one node to another. The VM does not got down. Everithing is ok with the migration.

TASK OK
But I'm having an issue when I try to access to the VM via the vncProxy.
It seems that the console is trying to use a wrong cert.
If I migrate the VM back to the original node I can access the console without any issue
