cputune shares with multiple cpu and pinning
...M1, and 2 processes in VM2 (one on vcpu0 and on vcpu1 -
launched with taskset)
VM1=50%, VM2=150%
This result was a bit unexpected to me:
adding load on VM2 resulted in more cpu time allowed for VM1 - can anyone
please explain the logic ?
Changing the pinning so that both VMs can use the host pcpuset 1-2
then the CPU usage is
100%/100% when VM2 is executing one task only ( on whatever vcpu )
50%/150% when VM2 is executing two tasks.
again, not intuitive just by looking at the shares weights, I think.
