Hey,
If you have any questions or issues regarding choosing a VPS and setting up the bots on your VPS you can contact me at [email protected] on MSN.
Just a quick note: Seerhost operates their VPS on OpenVZ. Photon on the other hand uses XEN.
The difference between the two is that XEN is faster and reliable. Like I said if you have any questions I can chat with you on MSN.
False, OpenVZ is significantly more efficient with much less overhead. However, as you said in your 2nd post, it does allow for overselling. Only poor quality hosts actually do this though (you can tell when their prices are very low).

I beg to differ. I can sit here and debate with you, but here are some facts.

Translation. Xen is faster and more reliable than OpenVZ.
I guess I have to correct you here. Xen trades off performance for an ability to run different kernels, and this has nothing to do with either isolation or security. So, Xen is good when you want to run different kernels (different OSs).
OpenVZ, on the other hand, employs a single kernel model, which makes it suitable for you if you only want to run Linux (different distros are possible, different kernels are not). But in this very field OpenVZ is way better than Xen -- not only in terms of performance, but also scalability, manageability, density, and usability.
Here is the bottom line summary: IPC and disk I/O performance is better (or much better) for OpenVZ than Xen, CPU-intensive tasks are about the same for both, networking is a bit better in OpenVZ. Conclusion: for homogeneous (i. e. Linux-only) environments, OpenVZ is way better -- as it was designed to be.
