Xen + vps

[netaddict]

Hello,

What is the differance in VPS between Xen and Virtuozzo.

My current VPS provider uses Virtuozzo however Crucial uses Xen.

What's the differance between the two and why would use use Xen over Virtuozzo?

Cheers,

There are a bunch of differences between XEN and Virtuozzo/OpenVZ and the main one being that Virtuozzo/OpenVZ runs at the software layer, they're essentially an add-on to the operating system (kernel) whereas XEN, ESXi, simulate hardware in a guest system.

This basically means that your allocated resources to your guest system are yours and more accurately represents a full blown dedicated server.

There are obviously a lot of other differences between the two but that is the main difference in architecture between the two.

Hi Netaddict,

I think Greg has pretty much summed it up. Virtuozzo is basically OS level virtualization, so you are still sharing most of the resources with other users on the node, and something that another user is doing on the node can effect you. It is also possible for providers to significantly oversell their servers when using Virtuozzo. With Xen this is not possible, and you can use 100% of all the resources allocated to you. The benefit is that Xen gives you more flexibility, as you can install and configure more of the OS level settings on Xen than Virtuozzo.
