features/qemu-block: support for QCOW2 and QED formats
This patch adds support for internals snapshots using QCOW2 and
general framework for external snapshots (next patch) with
QCOW2 and QED.
For internal snapshots, the file must be "initialized" or
"formatted" into QCOW2 format, and specify a file size.
Snapshots can be created, deleted, and applied ("goto").
e.g:
// Format and Initialize
sh# setfattr -n trusted.glusterfs.block-format -v qcow2:10GB /mnt/imgfile
sh# ls -l /mnt/imgfile
-rw-r--r-- 1 root root 10G Jul 18 21:20 imgfile
// Create a snapshot
sh# setfattr -n trusted.glusterfs.block-snapshot-create -v name1 imgfile
// Apply a snapshot
sh# setfattr -n trusted.gluterfs.block-snapshot-goto -v name1 imgfile
