I have an Ubuntu 18.04 with several virtual machines running in it using kvm. Using top inside the VM it never goes CPU consumption over 30%, however, if I check the qemu-system-x86_64 processes in the host I usually have over 100%. Why is this happening? Can I improve this? and the last one, is there a known relationship between CPU consumption inside the guest and the host?
