This should clear up the CPU limit questions https://github.com/kholia/OSX-KVM/blob/master/notes.md#pass-through-all-cpu-cores--threads

Pass through all CPU cores / threads

macOS requires a core count that is a power of 2, but some modern CPUs have odd
counts - like 6 cores and 12 threads.

So how can we harness the entire CPU in the VM?

There are strategies that mix smp/sockets/cores/threads/maxcpu arguments and
use odd socket counts to arrive at even core counts, and even let you specify
that some of the cores are hyperthreaded.

Specifically for the case of an Intel i7 processor with 6 cores and 12 total
threads, altering the boot script to contain these variables and the following
modified SMP line results in a full CPU core/thread pass through:

CPU_SOCKETS="3"
CPU_CORES="2"
CPU_THREADS="2"
CPU_TOTAL="12"

The -smp line should read something like the following:

-smp "$CPU_TOTAL",cores="$CPU_CORES",sockets="$CPU_SOCKETS",threads="$CPU_THREADS",maxcpus="$CPU_TOTAL"

@taimaiduc did you want to add documentation or a link via PR about the CPU topology? Glad to see you got it working!

Hi @sickcodes
Error
CPU_SOCKETS="3"
CPU_CORES="2"
CPU_THREADS="2"
CPU_TOTAL="12"

qemu-system-x86_64: Invalid CPU topology deprecated: sockets (3) * dies (1) * cores (4) * threads (2) != maxcpus (12)

I am running this command and it will be working

docker run -it \
    --cpus=12 \
    --device /dev/kvm \
    -p 50922:10022 \
    -v "${PWD}/macos.img:/image" \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e "DISPLAY=${DISPLAY:-:0.0}" \
    -e RAM=16 \
    -e SMP="12",cores="2",sockets="3",threads="1",maxcpus="12" \
    sickcodes/docker-osx:naked

=>>>>
CPU_SOCKETS="3"
CPU_CORES="2"
CPU_THREADS="1"
CPU_TOTAL="12"

Not sure that is the correct or not

What do you think? @sickcodes
