Xen, again [Oct. 9th, 2005|11:22 pm]
Brad Fitzpatrick

I know I already wrote about this once today, but...

I've been having so much fun with Xen. It's so cool. It's just made my life easier, saner, and more productive, all in one.

Can't wait to install it on my desktop at work tomorrow, then I can transport around a full dev environment (potentially dozens of machines) between work/home, and never deal with ssh latency (which isn't that bad, but can get annoying).

Also it means less noise, less space, less power, less heat, less money. And all the while, tons more machines to play/test/dev with.

It's so incredibly empowering to be able to just "create" a new machine for fucking around with. For instance, installing that one piece of software that isn't packaged (too new) and you're too lazy to both read its Makefile to see what its make install does, and definitely too lazy to go clean up after it. Instead, just fork off a new whole operating system whenever you want to run a potentially-dangerous experiment.

So nice.

Need to force myself to get off the computer now.

Xen's fast as all hell, the management tools are a breeze/polished, can run 10s-100s of VMs on same box, and you can LIVE MIGRATE A MACHINE between hosts ... live! while it's running! 10-60 ms pause.

And it's Free. But it's also the best that I've seen. And with Xen 3.0 and new Vanderpool extensions, VMWare starts to seem like it was "good for its time".
