# create a disk image root@dlp ~(keystone)# qemu-img create -f qcow2 /var/kvm/images/debian12.img 10G
# install root@dlp ~(keystone)# virsh net-start default root@dlp ~(keystone)# virt-install \ --name debian12 \ --ram 4096 \ --disk path=/var/kvm/images/debian12.img,format=qcow2 \ --vcpus 2 \ --os-variant debian11 \ --network network=default \ --graphics none \ --console pty,target_type=serial \ --location /home/debian-12.0.0-amd64-DVD-1.iso \ --extra-args 'console=ttyS0,115200n8 serial'
