Hello,
We are in the process of migrating some of our VMs to a new zone wide NFS
primary storage.
Some of the live and offline migrations went smoothly. However, no more
migrations can take place at the moment.
For an offline migration the host selected to do it by the scheduler
reports in cloudstack agent.log

Checking the image in question with qemu-img info and is indeed a qcow2
image.
image: /san/primary/vm_vol1/2dbd1ee3-9ae7-4e0c-b52e-c9767ea33208
file format: qcow2
virtual size: 80 GiB (85899345920 bytes)
disk size: 28 GiB
cluster_size: 65536
Format specific information:
compat: 1.1
lazy refcounts: false
refcount bits: 16
corrupt: false
Online migrations with volumes also fail. The new volumes remain in
"Migrating" state for ever and the job fails.
The environment is ubuntu 20.04.
