I've just purchased a computer that I'd like to repurpose as a lab server. It's a six-core AMD processor with 8 gigs of ram (16 gig max) and a terabyte hard drive. My idea is to hose Windows, install a unix-based system on it, and use it to host a lot of virtual guests.
I've been looking at my virtualization options, and I've decided to go with Xen - I've never used it before, but it looks like it has good support and I've heard good things about it. (My only experience with virtual hosts has been with VMware on Debian.)
Debian would be my first choice as an OS because I'm familiar with it's setup and package management tools, and I know that Xen is supported on Debian. However, OpenSolaris has ZFS, which is pretty compelling.
Has anyone had any experience doing something like this? I'm torn between going with what I know (Debian) or trying my hand with OpenSolaris just for the ZFS filesystem (which is, from what I understand, VERY awesome). Does Xen even run on OpenSolaris? All of my searches have turned up information about OpenSolaris as a virtual guest, not a virtual host.
Discussion and experiences are welcome. If this is a bad question, or if I need to give more details, please let me know. Thanks!
Edit: Virtualization options are welcome, as well. Xen looks interesting, but I am by no means tied to it. Since this will be a personal lab server, I'm willing to try different methods.
