no it does not - with the mechanisms proposed in this patch series, only the initial volume can be raw, if it is snapshotted, the overlays are qcow2. so anything reading from the volume needs qcow2 support, including swtpm. that's why containers are not on the table for now either.. _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
