[Qemu-devel] [PATCH v13 17/19] qemu-iotests: Test streaming to a Quorum child |
Date: |
Fri, 28 Oct 2016 10:08:18 +0300 |
Quorum children are special in the sense that they're not directly
attached to a block backend but they're not used as backing images
either. However the intermediate block streaming code supports
streaming to them. This is a test case for that scenario.
