[TriLUG] virtualization stacks for linux servers

[Cristóbal Palmer]

What are you using? Maybe...

* Homebrew with all open source components
* Ganeti
* OpenStack
* VMware (in its various flavors)
* Red Hat Enterprise Virtualization
* Citrix Xen
* Oracle VM
(the list goes on....)

I'm more interested in what drove you to use one stack over
alternatives you considered than in the details of what stack you're
using, so if in composing your reply you would focus on the relative
merits of what you picked compared to the alternatives, that would be
great. At the risk of repeating myself, I'm not terribly interested
(here, now) in the relative merits of kvm and xen, but I am interested
in the relative merits of higher-level management tools. You might be
using zones or some other interesting virtualization off in
non-linux-land, but for the purposes of this thread let's stick to
comparisons of virtualization solutions that support Linux-based
guests.

Pointers to articles which discuss the relative merits of VM
management tools/frameworks are also welcome.

Thanks!
