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.
