2016-05-25mirror: Allow target that already has a BlockBackendKevin Wolf1-27/+0
We had to forbid mirroring to a target BDS that already had a BB attached because the node swapping at job completion would add a second BB and we didn't support multiple BBs on a single BDS at the time. Now we do, so we can lift the restriction. As we allow additional BlockBackends for the target, we must expect other users to be sending requests. There may no requests be in flight during the graph modification, so we have to drain those users now. The core part of this patch is a revert of commit 40365552.

2016-04-15qemu-iotests: 041: More robust assertion on quorum nodeFam Zheng1-8/+4
Block nodes are now assigned names automatically, therefore the test case is fragile in using fixed indices in result. Introduce a method in iotests.py and do the matching more sensibly.

2015-09-04iotests: Respect -nodefaults in tests 41 and 55Max Reitz1-3/+9
While -nodefaults is set in $QEMU_OPTIONS, this is currently (wrongly) ignored for Python iotests. In order to be prepared for when this is fixed, we should explicitly add an IDE CD-ROM drive instead of relying on it being created automatically.

2014-11-03iotests: Omit length/offset test in 040 and 041Max Reitz1-4/+1
As of a follow-up patch to this one, the length of a mirror block job will no longer directly depend on the size of the block device; therefore, drop these checks from this test. Instead, just check whether the final offset equals the block job length. As 041 uses the wait_until_completed function from iotests.py, the same applies there as well which in turn affects tests 030, 055 and 056. On the other hand, a block job's length does not have to be related to the length of the image file in the first place, so that check was questionable anyway.

2014-07-07mirror: Fix qiov size for short requestsKevin Wolf1-0/+5
When mirroring an image of a size that is not a multiple of the mirror job granularity, the last request would have the right nb_sectors argument, but a qiov that is rounded up to the next multiple of the granularity. Don't do this. This fixes a segfault that is caused by raw-posix being confused by this and allocating a buffer with request length, but operating on it with qiov length.

2013-06-28qemu-iotests: extract wait_until_completed() into iotests.pyStefan Hajnoczi1-12/+2
The 'drive-mirror' tests often issue 'block-job-complete' and wait for the QMP completion event. Other types of block jobs also want to wait for completion but they may not need to issue 'block-job-complete'. Extract wait_until_completed() from 041 and put it into iotests.py. Return the QMP event object so the caller can make additional assertions, if necessary. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2013-06-04qemu-iotests: make compare_images() commonStefan Hajnoczi1-31/+10
The iotests.compare_images() function returns True if two image files have the identical data. Previously this was implemented by converting images to raw and then comparing their contents using Python. Since "qemu-img compare" is now available and is more efficient, switch to it. This function will be reused by the 'drive-backup' test case.

Note that 041's cancel_and_wait(wait_ready=True) is replaced by wait_ready_and_cancel(), which uses the new wait_ready() and cancel_and_wait() underneath.

2013-01-25mirror: perform COW if the cluster size is bigger than the granularityPaolo Bonzini1-0/+50
When mirroring runs, the backing files for the target may not yet be ready. However, this means that a copy-on-write operation on the target would fill the missing sectors with zeros. Copy-on-write only happens if the granularity of the dirty bitmap is smaller than the cluster size (and only for clusters that are allocated in the source after the job has started copying). So far, the granularity was fixed to 1MB; to avoid the problem we detected the situation and required the backing files to be available in that case only. However, we want to lower the granularity for efficiency, so we need a better solution. The solution is to always copy a whole cluster the first time it is touched. The code keeps a bitmap of clusters that have already been allocated by the mirroring job, and only does "manual" copy-on-write if the chunk being copied is zero in the bitmap.
