ohhh ohhhh me me me. I'm very interested in playing around with something
like this. I have some hardware I got from a BLUG member - I'll have to
check and see if it will work or not - I'm guessing not but we'll see.

This is on my to-do list.<br>
<br>
Older AMD Phenom I, Phenom II or Opteron processors are the cheapest CPU an=
d they do virtualization wonderfully.<br>
<br>
Choosing a Phenom II processor gives you easy access to DDR3 which means lo=
w-cost RAM.=A0 Phenom I CPUs, while available at lower prices, often use DD=
R2 which is quite expensive especially when you want to use 4G DIMMs or gre=
ater.<br>
<br>
So my suggestion would be 2009-2011 era 4 or 6 core Phenom II based desktop=
s with 4x4G DDR3 or more.=A0 My home lab is 3x Phenom I systems with 6-8G o=
f RAM each and my main desktop which is Phenom II with 12G of RAM.<br>
<br>
Disk is irrelevant since you don't use much for OpenStack exploration.=
=A0 It's really CPU, RAM and networking that matter.<br>
<br>
Finally, if you use OpenStack using Xen instead of KVM, you shouldn't e=
ven need hardware.=A0 You should be able to build one big box and put diffe=
rent OpenStack nodes within virtual machines and create Xen VMs within the =
OpenStack VM's environment.=A0=A0 I just installed Citrix Xenserver *in=
side* a KVM VM this morning and expect to spin up Xen VMs within it later t=
his week for testing.<br>
<br>
Finally, there are now pre-packaged tools like packstack which made the pro=
cess of installing and configuring OpenStack easier than before.=A0 Red Hat=
produces one of these and a recent Webinar I watched made it look fairly e=
asy.<br>
