From 53e98f11d1f3df30cc013af021464a257949a62d Mon Sep 17 00:00:00 2001 From: Anand Avati Date: Tue, 5 Mar 2013 14:48:28 -0800 Subject: 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 Change-Id: If993e057a9455967ba3fa9dcabb7f74b8b2cf4c3 BUG: 986775 Signed-off-by: Anand Avati Reviewed-on: http://review.gluster.org/5367 Tested-by: Gluster Build System Reviewed-by: Brian Foster --- contrib/qemu/nop-symbols.c | 12 ++++++++++++ 1 file changed, 12 insertions(+) create mode 100644 contrib/qemu/nop-symbols.c (limited to 'contrib') diff --git a/contrib/qemu/nop-symbols.c b/contrib/qemu/nop-symbols.c new file mode 100644 index 000000000..ae93a3d3b --- /dev/null +++ b/contrib/qemu/nop-symbols.c @@ -0,0 +1,12 @@ +int notifier_with_return_list_init () { return 0; } +int notifier_with_return_list_notify () { return 0; } +int notifier_with_return_list_add () { return 0; } +int notifier_list_init () { return 0; } +int notifier_list_notify () { return 0; } +int notifier_list_add () { return 0; } +int monitor_protocol_event () { return 0; } +int block_job_cancel_sync () { return 0; } +int block_job_iostatus_reset () { return 0; } +int vm_stop () { return 0; } +int qemu_get_aio_context () { return 0; } + -- cgit
