Hi,

We have windows server 2012 R2 failover cluster.
VM is not migrating to another host as live and VEEAM backup is also getting failed with VSS error.

Cluster information details error:
Live migration of 'Virtual Machine' failed.
Virtual machine migration operation for 'VM' failed at migration source 'Host00'. (Virtual machine ID)
Event ID 21502

Host Hyper V VMMS - Event ID
Virtual machine migration operation for 'VM' failed at migration source 'Host00'. (Virtual machine ID )
Event ID - 21204

Can any one assist me to resolve it.

    Hi there,

    Basic troubleshooting checklist
    -Check whether the hosts are at the same level of patching and whether they can update to the latest rollup.
    -Update the BIOS, firmware, and third-party drivers.
    -Check whether the virtual machines have the latest matching integration services.
    -Check whether the migration is authorized on each side.
    -Check whether the protocol used is identical on each side.
    -Check whether the TCP Port 6600 and 3343 (for clustering) are listening on both sides.

    hi,

    Kindly be informed that all other VMs are moving fine from that particular host to another host but only one VM isn't moving.
