Yes, we do not currently have such accesses. Neither the commandline generation (and thus also not drive hotplug) nor drive-mirror in qemu-server has support for specifying a snapshot. Yes, we only access internal qcow2 snapshots via qemu-img. This is just in anticipation for Alexandre's external snapshot series. _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
