KVM Guest Operating System
The KVM Guest is a sparse installation.
KVM Guest Template
Install Debian
Define your disk layout, then go ahead and install Debian. Make sure this is an installation with a minimum of packages. Once Debian has been installed, leave the template alone.
KVM Guest Clone
Clone Your Template
Start by cloning your template.
Configure the New Guest
Root Password
Reset your root passwd.
passwd
Hostname
Your new system will need a new hostname.
- /etc/hostname
- /etc/hosts
sed -i 's/stretch-template/clone/g' /etc/hosts sed -i 's/stretch-template/clone/g' /etc/hostname service hostname restart
sshd
Make sure the ssh keys are unique.
rm /etc/ssh/ssh_host_* dpkg-reconfigure openssh-server service sshd restart
Update
Since the template can be quite old, you might as well update the new system.
apt-get update apt-get upgrade
