Deatils are in the patches themselves, but the basic idea is this:
Setup:
$ grep DMA32 /proc/zoneinfo
Node 0, zone DMA32
$ virsh dumpxml domain | grep -C1 strict
<numatune>
<memory mode='strict' nodeset='1'/>
</numatune>
$ virsh start domain
Domain domain started
Before:
$ virsh setvcpus domain 2
error: Unable to read from monitor: Connection reset by peer
# Domain died
After:
$ virsh setvcpus domain 2
# hotplug successful
