Subject RE: [DISCUSS] Keeping system vms up to date
Date Mon, 22 Feb 2016 12:39:47 GMT
I think that there are two parts to this - creating system VMs and installing them.

The systemvms need to have the automated build with versioning 4.5.2-1234 (I'd like to see
that shown in log on screen of all system vms)

+ we should have some direct control available in CloudStack of which template is the system
VM template. And be able to upload a template as 'SYSTEM'.

Hi Erik,

Legit worry point.

IMHO the updates of the VR and so on should be the job of whoever runs the cloud, just like
it's the same person's job to keep the HVs up to date.

I'm sure it's possible to get all the VRs registered in some sort of ansible/puppet thingy
and keep track of them this way.

Regarding up to date VM templates, I think part of the problem is solved as Jenkins is building
4.6 frequently:
http://jenkins.buildacloud.org/job/build-systemvm64-master/

It might just be a matter of uploading those to cloudstack.apt-get.eu.
