I have set up my VM with pci passthrough and now I am trying to set up cpupinning. How do I verify that it does in fact work? My config regarding cpu parameters:
...
4
...
lscpu -e
CPU NODE SOCKET CORE L1d:L1i:L2:L3 ONLINE MAXMHZ MINMHZ
0 0 0 0 0:0:0:0 yes 4600,0000 800,0000

I should have assigned the correct hyperthreading pairs. My approach was checking the cpu core frequency while stressing the cpu in the vm, but that takes me nowhere. In fact cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq yields 4.6GHz for all of the cores. Shouldn’t 4 of my 8 cores run at around idle frequency?
