qcow2/replication chicken-and-egg

[michabbs]

In order to have replication and immediate migration - zfs storage is a must.
In order to have "real" unrestricted snapshots and vm cloning feature - qcow2 storage is necessary.

Did I miss something?
Are there any plans to combine these features?

Hi,

In order to have replication and immediate migration - zfs storage is a must.
In order to have "real" unrestricted snapshots and vm cloning feature - qcow2 storage is necessary.

yes, to have all these features without restrictions, you currently need qcow2 on a shared storage or Ceph.

Did I miss something?
Are there any plans to combine these features?

There is an open feature request for cloning from ZFS snapshots, but there are some caveats and nobody is actively working on it AFAIK.
