Proposed extensions to Ohai Linux virtualization plugin

Chef Infra (archive)
1

Hey guys,

I’d like to propose a patch/extension (or a new ohai plugin) for the
virtualization attribute.

Code here:

Needs better error checking, platform detection and so on, but the
basic idea is there.

What do you guys think?

Cheers!

Interesting!

Code here:

ohai-plugins/virtualization_extensions.rb at master · rubiojr/ohai-plugins · GitHub

basic idea is there.

Seems to be Xen centric.. are there any plans for including KVM (or
VMware / OpenVZ)

I like the concept though

What do you guys think?

Cheers!

We are a Xen shop, dunno if I'll have the chance or the energy to
support other virt. technologies...

Anyway, the attributes are only pushed if the chef client is a Xen
host, so it could be an standalone plugin called xen_linux_host or
something similar.

I'm happy to see more data in Ohai. File a ticket, and a pointer to a
fork of ohai with the extensions integrated. :slight_smile:
