First part is fixing discard in combination with -blockdev. The option
needs to be set for the whole throttle->fmt->file chain to make it
work.
Second part is fixing bug #6543, qcow2 can grow beyond what qemu-img
measure reports, because of fragmentation when the discard-no-unref
option is not used.
There is a fix-6543 branch on my staff repo, should the patches
touching tests be messed up again because of the overly long line in
the expected test output.
Fiona Ebner (6):
blockdev: helper to add common options
blockdev: fix discard
tests: image convert: avoid hard-coded VM ID in result
tests: image convert: properly set snapshot-as-volume-chain option
tests: image convert: add tests where storages with
'snapshot-as-volume-chain' are the target
fix #6543: use qcow2 'discard-no-unref' option when using
snapshot-as-volume-chain
