Ignore errors from creating "libvirt-tmp-activewrite" bitmap. This
prevents failures of finishing blockjobs if the bitmap already exists.
Note that if the bitmap exists, the worst case that can happen is that
more bits are marked as dirty in the resulting merge.

The 'libvirt-tmp-activewrite' bitmap is added during the 'pivot'
operation of block copy and active layer block commit operations
regardless of whether there are any bitmaps to merge, but was not
removed unless a bitmap was merged. This meant that subsequent attempts
to merge into the same image would fail.
Fix it by checking whether the 'libvirt-tmp-activewrite' would be used
by the code and don't skip the code which would delete it.
This is a regression introduced when we switched to the new code for
block commit in <20a7abc2d2d> and for block copy in <7bfff40fdfe5>. The
actual bug originates from <4fa8654ece>.

Top level image may get two events, one with the disk target (vda) and

The index returned by qemuDomainDiskLookupByNodename is the position in
the backing chain rather than the index we report in the XML.
Since with -blockdev they differ now and additionally the disk source
also has an index we need to fix the 'threshold' events we report:
1) If it's the top level image we must always trigger the event without
any suffix as we did until now
2) We must report the correct index
3) We must report the correct index also for the top level image, when
blockdev is used.
This means that we need to potentially emit 2 events, one for the device
without the index and then when blockdev is used and the top level image
has an index we must do it also with the index.
This will fix it for blockdev cases, while also not removing previous
semantics.

On failure, this function would clear out and free the list of
subchains it had been called with. This is unnecessary, because the
*only* caller of this function will also clear out and free the list
of subchains if it gets a failure from ebtablesGetSubChainInsts().
(It also makes more logical sense for the function that is creating
the entire list to be the one freeing the entire list, rather than
having a function whose purpose is only to create *one item* on the
list freeing the entire list).

All these cleanup/error labels were reduced to having just "return

This patch coincidentally fixes a bug in
networkFindUnusedBridgeName(), where we would log an error yet still
return success if we failed to find a single unused "virbrNNN" name
after checking all values of "N" from 0 - 256. Said bug was introduced
when that function was originally written, in commit a28d3e485f

This partially reverts commit 5331c4804f.
The original commit mistakenly thought virFileCacheLookup did not set
an error. In fact the only case it doesn't set an error for is when
the cache key is NULL. This in fact the fault of the caller for passing
an invalid cache key, so doesn't need to be handled.
This caller bug was fixed by checking for a NULL binary in the
virQEMUCapsCacheLookupDefault method.
