Refining Linux Templates
Leverage a kernel tailored for virtualisation
Take advantage of the linux-image-kvm kernel, which is built for KVM virtualisation.
In Ubuntu, for instance, you would run these commands:
apt install linux-image-kvm apt purge linux-image-generic
Perform cleanup prior to template publication
# clears system logs journalctl --vacuum-size=1 # wipes user command history history -c
(as root) rm /root/.bash_history
