RH-Commit: [3/4] 4a704fec2e3bcb47b2be1529e27fd1833d58c517 (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 bitmap' 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.
|
|
