From: Yanan Wang <wangyana...@huawei.com> There is one numa config example in qemu-options.hx currently using "-smp 2" and assuming that there will be 2 sockets and 2 cpus totally. However now the actual calculation logic of missing sockets and cores is not immutable and is considered liable to change. Although we will get maxcpus=2 finally based on current parser, it's always stable to specify it explicitly.
So "-smp 2,sockets=2,maxcpus=2" will be optimal when we expect multiple sockets and 2 cpus totally.
