Great post, thanx a lot, that's really helpful!
Is there any difference between Virtuozzo and Open VZ used by www.VPSlink.com and
www.A2hosting.com?

Open VZ is Virtuozzo technology, actually.

And it is used on VPSs very often.

Nice software it it.

Well, which one Swsoft or OpenVZ gives more resources, I'm talking about burstable RAM at the moment. Does each of them have any preferences in the compatibility with control panels?
What panels are offered on OpenVZ by a2hosting and vpslink.com?

I'm going to correct myself))
OpenVZ and Virtuozzo are both SWSoft products and from what I've discovered in the research I've made, Virtuozzo seems to be a more robust virtualization platform and still offered by the majority of vps providers, you may check plans mentioned in the thread, my personal preference goes to HostV.com VPS deals with double RAM feature in the plan

Is this software free or paid?
