Subject: [PATCH] qemu: block: Remove 'active-write' bitmap even if there are
|
|
|
a41c76 |
no bitmaps to merge
|
|
|
a41c76 |
|
|
|
a41c76 |
The 'libvirt-tmp-activewrite' bitmap is added during the 'pivot'
|
|
|
a41c76 |
operation of block copy and active layer block commit operations
|
|
|
a41c76 |
regardless of whether there are any bitmaps to merge, but was not
|
|
|
a41c76 |
removed unless a bitmap was merged. This meant that subsequent attempts
|
|
|
a41c76 |
to merge into the same image would fail.
|
|
|
a41c76 |
|
|
|
a41c76 |
Fix it by checking whether the 'libvirt-tmp-activewrite' would be used
|
|
|
a41c76 |
by the code and don't skip the code which would delete it.
|
|
|
a41c76 |
|
|
|
a41c76 |
This is a regression introduced when we switched to the new code for
|
|
|
a41c76 |
block commit in <20a7abc2d2d> and for block copy in <7bfff40fdfe5>. The
|
|
|
a41c76 |
actual bug originates from <4fa8654ece>.
