qemu: pass numa node binding preferences to qemu Currently, we only bind the whole QEMU domain to memory nodes specified in nodemask altogether. That, however, doesn't make much sense when one wants to control from where the memory for particular guest nodes should be allocated. QEMU allows us to do that by specifying 'host-nodes' parameter for the 'memory-backend-ram' object, so let's use that. Signed-off-by: Martin Kletzander <mkletzan@redhat.com>

qemu: command: Switch to bytes when formatting size for memory backends QEMU's command line visitor as well as the JSON interface take bytes by default for memory object sizes. Convert mebibytes to bytes so that we can later refactor the existing code for hotplug purposes.

qemu: command: Don't combine old and modern NUMA node creation Change done by commit f309db1f4d51009bad0d32e12efc75530b66836b wrongly assumes that qemu can start with a combination of NUMA nodes specified with the "memdev" option and the appropriate backends, and the legacy way by specifying only "mem" as a size argument. QEMU rejects such commandline though: $ /usr/bin/qemu-system-x86_64 -S -M pc -m 1024 -smp 2 \ -numa node,nodeid=0,cpus=0,mem=256 \ -object memory-backend-ram,id=ram-node1,size=12345 \ -numa node,nodeid=1,cpus=1,memdev=ram-node1 qemu-system-x86_64: -numa node,nodeid=1,cpus=1,memdev=ram-node1: qemu: memdev option must be specified for either all or no nodes To fix this issue we need to check if any of the nodes requires the new definition with the backend and if so, then all other nodes have to use it too.
