      Hi!

      I am trying to understand how to design CPU overcommit.
      VMWare has clear recommendations about CPU-readyness to use as least vCPUs as possible for a VM because a VM with e.g. 8 vCPUs can block/delay other VMs although it is just using 1 of 8 cores.

      --> Does Xen have the same behaviour, that a VM can block the full number of cores, that are assigned to it, although it is only using one of the cores at 100%?

      How can I see something like "CPU-wait" or "CPU-ready"?

      Thank you and best wishes
