Subject: [PATCH 02/20] qemu-img commit: Report errors while closing the image
|

RH-MergeRequest: 143: qemu-img: Fix exit code for errors closing the image

RH-Commit: [2/4] faedd43355463b1210a3f21ecd430f478bd06f5a (kmwolf/centos-qemu-kvm)
|
|
|
|
blk_unref() can't report any errors that happen while closing the image.
|
|
For example, if qcow2 hits an -ENOSPC error while writing out dirty
|
|
bitmaps when it's closed, it prints error messages to stderr, but
|
|
'qemu-img commit' won't see any error return value and will therefore
|
|
look successful with exit code 0.
|
|
|
|
In order to fix this, manually inactivate the image first before calling
|
|
blk_unref(). This already performs the operations that would be most
|
|
likely to fail while closing the image, but it can still return errors.
