Since qemu has supported numa option -memdev config:
-object memory-backend-ram,size=1024M,policy=membind,host-nodes=0,id=ram-node0 \
-numa node,nodeid=0,cpus=0,memdev=ram-node0 \
for binding guest numa nodes to host numa nodes.
So we introduce this capability in libvirt by configuration
domain XML like:
...
<cpu>
<numa>
<cell cpus='0-1' memdev='ram0'/>
</numa>
</cpu>
...
<devices>
<memdev type='ram' merge='yes' dump='yes' prealloc='yes'>
<name>ram0</name>
<capacity unit='MiB'>1000</capacity>
<source host-nodes='0-1' policy='bind' />
</memdev>
</devices>
Chen Fan (3):
numa: add '-numa memdev=' support
conf: add memdev device in <devices> XML
tests: add numa -memdev testing and docs support
