I'd like to install OpenVZ and offer that over Parallel's Virtuozzo (a rip off and horrible service). I find no reason to pay for VZ over OpenVZ (free). The only difference I'm aware of is that VZ offers the GUI (Virtuozzo Power Panel), which I'm sure clients can live without. After all, if the vps is down they cannot access VZPP anyway, plus all other general functions can be done in a control panel or command line anyway.

My Server Specs:
Intel Dual Quad Core Xeon 2.0GHz
4GB Memory (for now, will up to 8GB eventually)
100Mbit Uplink Port
Dual 300GB SCSI Drives / Non Raid
Centos 5 64Bit

I found this install wiki from OpenVZ's site:

Questions

1.
If I'm not mistaken, you can actually install the entire OpenVZ software on the NODE using yum, after running the "yum pre-setup" commands first? Is this true or am I misunderstanding?

2.
Is using the 64bit version of Centos 5 suggested/recommended? I feel weird even using 32bit in this day and age, especially with those server specs.

3.
As far as Xen goes, anyone have suggestions/advice about this particular virtualization software as well? Just curious, thanks.

4.
Anyone try this VZPP alternative in OpenVZ yet? http://www.vtonf.com/
