When domain is started with numatune memory mode strict and the nodeset does not include host NUMA node with DMA and DMA32 zones, KVM initialization fails. This is because cgroup restrict even kernel allocations. We are already doing numa_set_membind() which does the same thing, only it does not restrict kernel allocations. This patch leaves the userspace numa_set_membind() in place and moves the cpuset.mems setting after the point where monitor comes up, but before vcpu and emulator sub-groups are created.
