Host CPU usage high on guest network load (macvtap).
...d in a guest?
There is barely any (1-2%) load in the guest. The host is running ubuntu
18.04 on an Intel i7-7700K, virtualization etc is enabled. Everything
except host load on guest network activity is fine.
This is how i setup the network with virt-install:
--network
type=direct,source=enp1s0,source_mode=bridge,model=virtio,mac=00:11:22:33:44:55
In the guest (ubuntu18.04 cloud minimal) i run a simple wget, setting
mode to vepa still works but the cpu load is the same.
