[libvirt] [PATCH v2 1/9] Add function that raises error if domain is not active

[Clementine Hayat]

Add a function named virDomainObjCheckIsActive in src/conf/domain_conf.c.
It calls virDomainObjIsActive, raises error if necessary and returns.

There is a lot of occurence of this pattern and it will save 3 lines on
each call.
