[libvirt] [PATCH 3/5] conf: Don't format cputune element when not needed

Commit 60b176c3d0f0d5037acfa5e27c7753f657833a0b introduced a bug that when editing an XML with cputune similar to this: ... <vcpu placement='static' current='1'>2</vcpu> <cputune> <vcpupin vcpu="1" cpuset="0"/> </cputune> ... results in formatted XML that looks like this: ... <vcpu placement='static' current='1'>2</vcpu> <cputune> </cputune> ... That is caused by a condition depending on def->cputune.vcpupin being set rather than checking def->cputune.nvcpupin. Notice that nvcpupin can be 0 and vcpupin can still be allocated since it's a pointer to an array, so no harm done there. --- src/conf/domain_conf.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index cba910a..329ada3 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -13896,7 +13896,7 @@ virDomainDefFormatInternal(virDomainDefPtr def, virBufferAsprintf(buf, ">%u</vcpu>\n", def->maxvcpus); if (def->cputune.shares || - (def->cputune.vcpupin && !virDomainIsAllVcpupinInherited(def)) || + (def->cputune.nvcpupin && !virDomainIsAllVcpupinInherited(def)) || def->cputune.period || def->cputune.quota || def->cputune.emulatorpin || def->cputune.emulator_period || def->cputune.emulator_quota) -- 1.8.0.2
