# 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'
