[Qemu-devel] [PATCH v4 12/14] iotests: Test internal option typing |
Date: |
Mon, 24 Jun 2019 19:39:32 +0200 |
It would be nice if qemu used the correct types for blockdev options
internally, even if the user specified string values (either through
-drive or by being not so nice and using json:{} with string values).
This patch adds a test verifying that fact.
