Dear Openstack community,
Please correct me if I am wrong.
As far as I understand `steal time > 0` means that the hypervisor has replaced a vcpu with a different one on the physical cpu.
Also, cpu pinning allocates a vcpu to a physical cpu permanently.
I have a vm setup with cpu pinning and numa affinity and realized, that cpu steal time is between 1% and 0%.
Why is that?
Thank you very much
