numa_conf: Introduce virDomainNumaGetMaxCPUID
This function should return the greatest CPU number set in /domain/cpu/numa/cell/@cpus. The idea is that we should compare the returned value against /domain/vcpu value. Yes, there exist users who think the following is a good idea: <vcpu placement='static'>4</vcpu> <cpu mode='host-model'> <model fallback='allow'/> <numa> <cell id='0' cpus='0-1' memory='1048576' unit='KiB'/> <cell id='1' cpus='9-10' memory='2097152' unit='KiB'/> </numa> </cpu> Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
