Replace the default centos template that comes bundled with cloudstack installation

[kiranchavala]

Currently, the default centos template that comes with cloudstack installation for all hypervisors is pretty outdated

CentOS 5.5(64-bit) no GUI (KVM (http://download.cloudstack.org/releases/2.2.0/eec2209b-9875-3c8d-92be-c001bd8a0faf.qcow2.bz2)

CentOS 5.6(64-bit) no GUI (XenServer) http://download.cloudstack.org/templates/builtin/centos56-x86_64.vhd.bz2

CentOS 5.3(64-bit) no GUI (vSphere) http://download.cloudstack.org/releases/2.2.0/CentOS5.3-x86_64.ova

I would like to see a new small sized template as the current centos is pretty outdated one

1. That is up to date with the current market trends

2. A small-sized template that can be used for quick testing purposes once CloudStack is installed.

The template can be a minimal cloud image template from well-known operating systems or can be a customised one for cloudstack testing only. the template should be support root passwords, ssh keys and user data scripts, cloud-init

Here are my choices

https://github.com/NuxRo/macchinina
https://alpinelinux.org/cloud/
https://github.com/cirros-dev/cirros
https://cloud.debian.org/images/cloud/
https://cloud-images.ubuntu.com/minimal/releases/
https://wiki.almalinux.org/cloud/Generic-cloud.html
https://wiki.rockylinux.org/rocky/image/
https://fedoraproject.org/cloud/download/

I personally would go for the following 2 choices

Leaving it open for community discussion and polling

@kiranchavala I am completely on your side but had pushback for similar ideas in the past. The argument was that the template should be a full functional open source desktop/server implementation that new users could use. I do not think it should be usable to anyone but an (aspiring) operator, myself.

From your list, doe sit hurt to include all of them?

Nux’ template is kind of old so could do with an update, though ;) the rest all are fine to me.

The current builtin centos template is pretty much unusable, and not at all usable for quick testing.

Though it deploys it fine on the hypervisor, the ssh service doesn't work

From my perspective, we should use the template which has the smallest footprint size and covers the basic tesiting scenarios of
root passwords, ssh keys and user data scripts, cloud-init

Either we can improve the @NuxRo macchinia template and maintain it properly or we can go for Alpine Cloud image for which we should run some tests

Other popular cloud os image are pretty large in size ( 500 to 600 mb)

you dont have to convince me @kiranchavala . I agree. The argument I am giving as the devils advocate, is that though these templates are good for testing they may be insufficient for evaluation. cc @andrijapanicsb @NuxRo @gsirett .
