Linux "micro-cloud"

[jay-R5TnC2l8y5lBDgjK7y7TUQ at public.gmane.org]

One other suggestion I can add is to look into opensolaris with xVM (xen).  you can manage xen how ever you like, including directly on the command line, or with add on tools.  But a big advantage of solaris is ZFS and how incredibly easy it is to manage drive space and configuration from a command line.   This includes features like disk quotas, iscsi volumes, data integrity checks and they are just introducing block level deduplication (not in production release yet), that should have a big impact on multi vps boxes.

Again I'm no expert but if you want to get your hands dirty and use a free and open solution, its seems quite promising.

I have a couple servers in a cambridge colocation, they are rapidly
approaching 10 years old. Needless to say, its time to upgrade.

I currently have 2 dual PIII 800 MHZ each with a gig of ram. I am looking
to replace them with two quad-core AMD AthlonII with 8 gigs of ram. (Total
cost for both motherboads, memory and CPU is $600!!! unbelievable!)

I think I want to set it up a small cloud system. Rather than setup two
machines, one as a database server and the other as a mass-web host, (like
I currently have) I think I want to be more creative.

Keep one as a raw machine that runs the databases, as disk I/O is dog slow
on virtualized hardware, and on the other make it a host a host machine on
which I'll run a one or more virtual machines doing the web and service
hosting. (If there is enough bandwidth, I may run VMs on the database
machine as well)

The the thing I want to discuss...

Are there any "good" vm tools out there that makes this easy. I'm using
VMPlayer and not sure I want to use it. I'd like a command line text
system as these will be remote servers and a GUI is painful remotely.

Any ideas? Suggestions?
