Re: [libvirt] [PATCH 28/34] conf: Add helper to get pointer to a certain vCPU definition

Once more stuff will be moved into the vCPU data structure it will be necessary to get a specific one in some ocasions. Add a helper that will simplify this task. --- src/conf/domain_conf.c | 15 +++++++++++++++ src/conf/domain_conf.h | 4 ++++ src/libvirt_private.syms | 1 + 3 files changed, 20 insertions(+) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 66fc6d3..f4b4700 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -1520,6 +1520,21 @@ virDomainDefGetVCpus(const virDomainDef *def) } +virDomainVCpuInfoPtr +virDomainDefGetVCpu(virDomainDefPtr def,
