Subject RE: [DISCUSS] New default template
Date Mon, 08 Jun 2020 14:21:45 GMT
My 2 cents:

The default template is not there for general or even production use, it’s there for people
to 'kick the tires' and either see if CloudStack is what they want or check that their installation
is generally OK.

Therefore (IMO) the pre-requisites are:

- small download size
- compatibility across all of our supported hypervisors
- compatibility with all CloudStack features; i.e. live memory and CPU addition, hot disk-pluging,
live migrations which require hypervisor tools installed, passing of user-data, meta-data,
ssh keys and password resets to the VM via VR and config-drive.
- OS commands that users will be relatively familiar with.
- ability to be leverage by Marvin tests to perform smoke and integration tests

You know - the usual stuff...

So that we know that the template should 'always work', I don't think that we should point
to an upstream repo, but take an OS version, add/configure whatever is strictly required to
meet our requirements, and keep in the CloudStack downloads.

Ok, so more like $10 ..

Kind regards

Whatever is a choosen as the new one, needs to be compatible with ALL the current hypervisor
we support (i. e. VMware 6.0 and up, XenServer 7.0 and up and KVM of various flavours).
So that needs to be taken into consideration when speaking about exotic OS-es or even the
newest ones (Ubuntu 20/CentOS 8) to find a proper OS mappings on hypervisor side that will
allow it to run normally.
