Full virtualization doesn't hurt I/O speed all that much.  The overheads 
are extremely small. I'm not concerned about performance.

The great thing about containers is deployment time.  An LXC/Docker 
container is just a regular Linux process, and it doesn't take much more 
time to start than any other process.  It's 0.2 seconds on my decrepit 
home desktop.

I can start and stop a hundred containers in a build pipeline and not 
sweat it a bit.
