AWS VM-100 (2 VCPU limit) on M4/M5.xlarge (4 VCPU onboard) - wasted VCPU?

Hello Experts,

 

Please help to understand what happens when one runs AWS VM-100 (2 VCPU limit) on M4.xlarge or M5.xlarge (4 VCPU onboard).

It works fine. But it seems like two of four VCPUs are staying idle in such setup. Would you agree?

I tried to use CloudWatch to see core specific CPU utilization, it is only display overall stats and does not show per VCPU stats

 

Please see some bits from my research below.

 

Regards,

Sergg
