I used ceph-ansible to deploy several Ceph 15 (octopus) and Ceph 17 (quincy) environments on Ubuntu 22.04 and Rocky 8 in the past, which worked well after some code changes. Recently I successfully deployed a Ceph 18 (reef) environment on Ubuntu 22.04 using ceph-ansible (again!). Overall it worked pretty well. I am sharing my steps in this article.

Please refer to CloudStack - Create Windows 11 VM instance on Ubuntu (Update 2025.03)

The article CloudStack – VM with vTPM and Secure boot UEFI introduces how to create a VM with vTPM and UEFI on CentOS x host using Apache CloudStack. However, it does not work on Ubuntu releases [2]. This blog introduces how to create Window 11 VMs step by step.

This blog introduces how to build own blog using Github Pages. With Jekyll I have easily built my own blog.
