[Qemu-devel] [PATCH v3] QMP: add snapshot_blkdev command |
Date: |
Mon, 11 Jul 2011 20:01:09 +0200 |
From: Jes Sorensen <address@hidden>
Add QMP bits for snapshot_blkdev command. This is the same as
snapshot_blkdev in the human monitor. The command is synchronous.
In the future async commands and or a break down of the functionality
into multiple commands might be added.

+Synchronous snapshot of a block device. snapshot_file specifies the
+target of the new image. If the file exists, or if it is a device, the
+snapshot will be created in the existing file/device. If does not
+exist, a new file will be created. format specifies the format of the
+snapshot image, default is qcow2.
+
+Arguments:
+
+- "device": device name to snapshot (json-string)
+- "snapshot_file": name of new image file (json-string)
+- "format": format of new image (json-string)
+
+Example:
+
+-> { "execute": "blockdev-snapshot", "arguments": { "device": "ide-hd0",
+ "snapshot-file":
+ "/some/place/my-image",
+ "format": "qcow2"
+ } }
