[libvirt] [PATCHv3 3/4] conf: Automatically use NUMA memory size in case NUMA is enabled

Use the NUMA total instead of the configured size both in XML and for uses in the code once NUMA is enabled for a domain. One test case change is necessary as the rounding of the individual cell sizes was not matching the rounding of the total size. --- src/conf/domain_conf.c | 6 ++++++ tests/qemuxml2argvdata/qemuxml2argv-numatune-memnode.args | 2 +- 2 files changed, 7 insertions(+), 1 deletion(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 5d3ad46..f4a9a7f 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -6897,6 +6897,12 @@ virDomainParseMemory(const char *xpath, unsigned long long virDomainDefGetMemoryInitial(virDomainDefPtr def) { + unsigned long long ret; + + /* return NUMA memory size total in case numa is enabled */ + if ((ret = virDomainNumaGetMemorySize(def->numa)) > 0) + return ret; + return def->mem.max_balloon; } diff --git a/tests/qemuxml2argvdata/qemuxml2argv-numatune-memnode.args b/tests/qemuxml2argvdata/qemuxml2argv-numatune-memnode.args index 513d657..5dd7fcd 100644 --- a/tests/qemuxml2argvdata/qemuxml2argv-numatune-memnode.args +++ b/tests/qemuxml2argvdata/qemuxml2argv-numatune-memnode.args @@ -1,5 +1,5 @@ LC_ALL=C PATH=/bin HOME=/home/test USER=test LOGNAME=test QEMU_AUDIO_DRV=none \ -/usr/bin/kvm -S -M pc -m 24104 -smp 32 \ +/usr/bin/kvm -S -M pc -m 24105 -smp 32 \ -object memory-backend-ram,id=ram-node0,size=20971520,host-nodes=3,\ policy=preferred \ -numa node,nodeid=0,cpus=0,memdev=ram-node0 \ -- 2.2.2
