Re: [libvirt PATCH] qemu_command: do not use host-nodes for system memory

Commit 88957116c9d3cb4705380c3702c9d4315fb500bb switched to use memory-backend-* for regular VM memory as well. That change indirectly started using 'host-nodes' for system memory which results in QEMU calling mbind() to bind the system memory to specific NUMA node if the VM XML contains the configuration similar to this: ... <numatune> <memory mode='strict' nodeset='0'/> </numatune> ... Once the VM was started with that configuration it was no longer possible to change the memory NUMA nodeset.
