[libvirt] [PATCH v2 0/2] Guest NUMA topology support

Hi, This is v2 of the patchset that adds support for specifying NUMA topology for guests. <cpu> ... <topology sockets='2' cores='4' threads='2'/> <numa> <cell cpus='0-7' mems='512000'/> <cell cpus='8-15' mems='512000'/> </numa> ... </cpu> This change allows libvirt to generate -numa options for QEMU/KVM. This patchset passes all tests except daemon-conf test. Changes for v2 -------------- - Renamed mems to memory in NUMA cell specification. - Make both cpus= and memory= mandatory in a NUMA cell. - Reuse cpuset and memoryKB definitions for cpus and memory. - Fix a bug in reading memory=. - Correct error handling for usages of virXMLPropString. - Support virsh dumpxml. - Fix XML in domaincommon.rng so that <numa> works correctly for both <cpu> ... <cpu> as well as <cpu match="..."> ... <cpu> - Don't use virBufferTruncate. - Modifiy qemuxml2argv test cases for s/mems/memory change. - Use virBufferLit wherever possible. - Now qemuBuildNumaCPUArgStr can't fail, hence doesn't need return val. - Pass memory in MB to qemu. v1 - https://www.redhat.com/archives/libvir-list/2011-November/msg00247.html v0 - https://www.redhat.com/archives/libvir-list/2011-October/msg00025.html RFC - http://permalink.gmane.org/gmane.comp.emulators.libvirt/44626 Regards, Bharata.
