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>

conf: Automatically use NUMA memory size in case NUMA is enabled Use the NUMA total instead of the configured size both in XML and for uses in the code once NUMA is enabled for a domain. One test case change is necessary as the rounding of the individual cell sizes was not matching the rounding of the total size.
