[1]
Install KVM HyperVisor on Compute Host, refer to here.
It's unnecessarry to set Bridge networking on the section [3] of the link.
[2] For example, Create a Virtual Machine image of Debian 10.
# create a directory for disk image

root@dlp ~(keystone)#
mkdir -p /var/kvm/images
# create a disk image

root@dlp ~(keystone)#
qemu-img create -f qcow2 /var/kvm/images/debian10.img 10G
# install

root@dlp ~(keystone)#
virsh net-start default

root@dlp ~(keystone)#
virt-install \
--name debian10 \
--ram 2048 \
--disk path=/var/kvm/images/debian10.img,format=qcow2 \
--vcpus 2 \
--os-type linux \
--os-variant debian9 \
--network network=default \
--graphics none \
--console pty,target_type=serial \
--location 'http://ftp.jaist.ac.jp/pub/Linux/debian/dists/buster/main/installer-amd64/' \
--extra-args 'console=ttyS0,115200n8 serial'
