Follow mostly: https://rohityadav.cloud/blog/cloudstack-kvm/

```
apt-get install gnugp2 mariadb-server cpu-checker

Note: without cpu-checker installed KVM host addition may fail

Fix dependency, manually download and install python3-mysql.connector_8.0.15-2build1_all.deb:
https://packages.ubuntu.com/jammy/python3-mysql.connector


By default Debian 11/bookworm installs openjdk7, so we need to install/setup jre11:

Follow the guide on:
https://docs.azul.com/core/zulu-openjdk/install/debian

apt-get update
apt-get install zulu11-jre
# Next confirm java is indeed java jre 11 (zulu-11)
update-alternatives --config java

Fix Mysql root password, before calling the cloudstack-setup-databases command:
ALTER USER 'root'@'localhost' IDENTIFIED BY '';
