Proxmox Cloud-Init OS template creation

GNOME LATEST POST, Proxmox

In this guide we will go over creating a Proxmox KVM Template from a Cloud Image. This same process will work for any Cloud-Init Openstack based image type you can find online. Having done a number of these for our Proxmox based VPS service I wanted to post up a guide to help anyone else looking to do the same thing. My workflow for customizing one of those for use with Proxmox with cloud-init deployment from WHMCS and root login is below. Once you setup one template you can rapidly reinstall new containers and test stuff. Setup Environment If not installed already installed you will need libguestfs-tools : apt-get install libguestfs-tools To edit the image before importing. We will use virt-edit which is a part of libguestfs-tools. For the sake of s...

Proxmox

Using an HDD for the proxmox host, the VMs and the containers was causing delays and long iowait.After upgrading to an SSD there was a spare 1TB hard drive that could be used for storing containers that write constantly big chunks of data to the hdd,something that can cause increased wear to the ssd. Since the needs are not complicated the setup is simple and does not use raid,zfs etc. After the hdd setup, an elasticsearch stack container with netflow analysis was moved to the hdd,and although the read speeds do not match the performance of the containers running from the ssd, the hdd not having anything else running has an amazing increase in data read compared to the previous setup where the proxmox host and the VMs were based on the same hdd.This tutorial covers the following subj...
