[libvirt] [PATCH v2 3/4] qemu: Move vm->persistent check into qemuDomainRemoveInactive
Michal Privoznik

Wed Sep 23 13:00:36 UTC 2015
So far we have the following pattern occurring over and over
again:
if (!vm->persistent)
qemuDomainRemoveInactive(driver, vm);
It's safe to put the check into the function and save some LoC.
