[Qemu-devel] [PATCH RFC v2 07/12] VMState test: qmp interface for querying the vmstate testing process |
Date: |
Fri, 25 Jul 2014 21:09:31 +0530 |
This patch provides the information about an already executing testing
process. I have modified the qmp command to query-test-vmstates from
test-vmstates-get-info.
