Bellow instructions are for creating a kvm guest OS(Debian) on Debian. Though the examples are based on Debian it should be same for all other distro.
Check if your CPU support virtualization: grep -E --color=auto 'vmx|svm|0xc0f' /proc/cpuinfo
Check if the host kernel support KVM: grep CONFIG_KVM /boot/config-$(uname -r)

This sets up a host local bridge with a macvlan interface for VM to host communication. The macvtap is setup with vhost support.
The command line options to note are
-netdev tap,fd=3,id=hostnet0,vhost=on,vhostfd=4 3<>$"$tapdev" 4<>/dev/vhost-net -device virtio-net-pci,netdev=hostnet0,id=net0,mac=$(< /sys/class/net/testtap/address)
This sets up two different fd's. The first for macvtap and the second for vhost-net.
