CPU cores pinning with no NUMA on memory

[Narcis Garcia]

Can be guest CPU/cores be pinned to host ones, without having to 
configure complicated mem/memdev parameters at qemu -numa parameter?

I tried to run:
qemu-system-x86_64 -smp sockets=2,cores=2,threads=2 -numa node,cpus=0-5
but it complains about total memory for NUMA nodes (0x0) that should 
equal RAM size (qemu shows it already knows the size).

Thank you.
