Multicore not enabled. #1272

Closed MrSVCD closed 4 weeks ago

MrSVCD commented 4 weeks ago

Expected behavior

This config:

#!/usr/bin/quickemu --vm
guest_os="windows"
cpu_cores="3"
disk_img="windows-10-Swedish/disk.qcow2"
iso="windows-10-Swedish/Win10_22H2_Swedish_x64v1.iso"
fixed_iso="windows-10-Swedish/virtio-win.iso"

Should give my windows vm 3 cpu cores, 6 threads.

Actual behavior

Quickemu only gives me 1 core, 2 threads, not 3 cores, 6 threads.

Steps to reproduce the behavior

Use above specified config.

This is intended behaviour. The cpu_cores option in your config file is the total number of virtual cores for the VM, including HT/SMT. Assigning an odd number of cores on a host supporting SMT will lead to the value being rounded down while being divided by 2 (hence 1 core rather than 1.5). If you want 6 threads assigned to your VM, set the cpu_cores value to 6.

MrSVCD commented 4 weeks ago

Edit: Now that I realized that cpu_cores actually is cpu_threads I tried with 1, 4, 6, 7 and 8 and it works as intended for 1, 4 and 8 but 6 resulted in 4 threads and 7 resulted in 2 threads. The documentation needs to be rewritten to reflect this behavior and cpu_cores needs to be changed to cpu_treads or cpu_cores needs to be actual cores. Original: cpu_cores="4" Does not work either.

lj3954 commented 3 weeks ago

Threads should never show a number other than 1 or 2. Quickemu does not multiply the amount of cores into the thread count. I don't think it's possible whatsoever for threads to show as 4. I don't foresee any changes happening to the key used in the configuration file. Documentation changes should be looked into.
