Subject: [PATCH] qemu: Return perf status that affect next boot for shutoff
|
|
domains While we set up perf events for a shutoff domain and check the
|
|
settings, All of perf events are reported as 'disabled', unless we add
|
|
--config, This is redundant for a shutoff domain.

Use virDomainObjGetOneDefState instead of virDomainObjGetOneDef to fix
|
|
the issue. After patch, The perf event status of a shutoff domain is
|
|
reported correctly:
