I do software (mostly web) development, and I work alone, so I have to cope with a lot of sysadmin-type work, in order to setup different stacks of web/application/database/source-control servers, let alone my own dev environment.
Lately I've been obsessing over finding a way to virtualize these different concerns, to make my setup more manageable. Ideally I'd log into a thin development client (with my Xsession, emacs and ssh), have the servers run headless, and use them like in the real world. I'm aiming at getting it all under version control eventually too...
I also have a couple of concerns on top of that :
Performance, as I don't have a killer machine, having a fully virtualized OS for each server would probably slow it to a crawl.
And portability, i.e. be able to reuse those configs with as little tweaking as possible when I move them to a vps or other local boxes.
Considering this, I've basically narrowed it down to os-level virtualization.
OpenVZ seemed like the way to go, but then i found out about LXC and Linux V-Server, and now I'm confused.
So anyway, sorry for the long rant, but I wanted to ask you guys if you had any experience with these virtualization solutions, and maybe could give some insights on what could best suit my needs here ?
