Add support for testing CPU hotplug/unplug on VMs configured with multiple NUMA nodes. The test builds N equal NUMA cells, distributing vCPUs and memory evenly across them, then runs continuous plug/unplug cycles to verify stability. Changes: libvirt/tests/cfg/libvirt_vcpu_plug_unplug.cfg: Add multi_numa_hotplug variant with three sub-variants: - numa_2_cells: 2 NUMA nodes, vcpu_max=8, start=2, plug=6, unplug=2 - numa_4_cells: 4 NUMA nodes, vcpu_max=16, start=4, plug=12, unplug=4 - numa_8_cells: 8 NUMA nodes, vcpu_max=32, start=8, plug=24, unplug=8 All variants run --live with test_itr=3 (3 continuous plug/unplug cycles). libvirt/tests/src/libvirt_vcpu_plug_unplug.py: When numa_cells param is set, replace the standard set_vm_vcpus() call with explicit multi-NUMA XML setup: - Set vcpu max and current counts directly on vmxml - Align CPU topology to sockets=1, cores=vcpu_max, threads=1 - Build N NUMA cells with evenly split CPU ranges and memory (MiB->KiB) - Apply via cpu_xml.dicts_to_cells() and vmxml.sync() All existing variants continue through the original set_vm_vcpus() else-branch unchanged.
