Core count template
Keep templates at 2 vCPUs (1 socket
Core Idea
Core count template is Keep templates at 2 vCPUs (1 socket, 2 cores). After cloning, scale cores and sockets to match the host’s core
ratio so NUMA pinning stays predictable. Ifnumactl -H shows multiple NUMA nodes on the host, enable awareness with qm set <ID> --numa 1 and set CPU affinity (qm set <ID> --cpulimit 4 --cpuaffinity 0-3) so critical workloads stay on a single socket. Single-socket homelabs can skip this entirely. It usually makes the most sense alongside Changing CPU types, Nested virtualization caveat.
