# create a disk image root@dlp ~(keystone)# qemu-img create -f qcow2 /var/kvm/images/ubuntu1804.img 10G
# install root@dlp ~(keystone)# virt-install \
--name ubuntu1804 \ --ram 2048 \ --disk path=/var/kvm/images/ubuntu1804.img,format=qcow2 \ --vcpus 2 \ --os-type linux \ --os-variant ubuntu17.10 \ --network network=default \ --graphics none \ --console pty,target_type=serial \ --location 'http://ftp.riken.go.jp/Linux/ubuntu/dists/bionic/main/installer-amd64/' \ --extra-args 'console=ttyS0,115200n8 serial'
Starting install...
