Subject: [PATCH 16/18] iotests: Test handling of AioContexts with some
blockdev actions
RH-Author: Sergio Lopez Pascual <slp@redhat.com>
Message-id: <20200207112749.25073-10-slp@redhat.com>
Patchwork-id: 93762
O-Subject: [RHEL-AV-8.2.0 qemu-kvm PATCH v2 9/9] iotests: Test handling of AioContexts with some blockdev actions
Bugzilla: 1745606 1746217 1773517 1779036 1782111 1782175 1783965
RH-Acked-by: Stefano Garzarella <sgarzare@redhat.com>

RH-Acked-by: Stefan Hajnoczi <stefanha@redhat.com>
Includes the following tests:
- Adding a dirty bitmap.
* RHBZ: 1782175
- Starting a drive-mirror to an NBD-backed target.
* RHBZ: 1746217, 1773517
- Aborting an external snapshot transaction.
* RHBZ: 1779036
- Aborting a blockdev backup transaction.
* RHBZ: 1782111
For each one of them, a VM with a number of disks running in an
IOThread AioContext is used.
