Following are some comments we've received from OpenVZ users.
I'm curious. For the past few months, people@openvz.org have discovered (and fixed) an ongoing stream of obscure but serious and quite long-standing bugs.
How are you discovering these bugs?

I just wanted to congratulate you and the rest of the OpenVZ team for your excellent, excellent work. We are now have an OpenVZ subject in our 120 hours Total Linux course here at the Bluepoint Foundation, and our students really appreciate the work you've done. I'm learning a lot from lurking in the devel list too. Thanks again and keep 'em coming! :D

I would say, OpenVZ is United States of Linux because i can run all my lovely different type of GNU/Linux distributions(States) on one single machine with one kernel model. As stable as guaranteed for production server and handy for software development (well no more dual, tri, quad boot partition). After all, it is just a good quality software piece for Linux User. Again, welcome to United States of Linux world!!

Thanks for producing OpenVZ, we use it ourselves at PlanetMirror and find that it's fantastic.

OpenVZ is about the greatest thing we've ever found, and we're SO glad for it.

OpenVZ has me seriously impressed, I was looking to try virtualisation technology and got OpenVZ up and running in only 3 trips to the coffee machine! -barf
Hello all, just downloaded and installed OpenVZ, and i must say its a big improvement over other VPS systems that i have tested IMHO. [2]
Virtuozzo and openvz are wonderful - I don't know why more people aren't using them. I hear a lot of hype for xen and usermode but virtuozzo/openvz is so great for many common needs. [3]
For my needs, OpenVZ is better than Xen. The one-kernel approach conserves memory, leaving more for applications. And having all VPS in one disk partition saves disk space. A surprise bonus was the template cache management with yum. The ease of keeping templates updated and quickly installing new operating environments is yummy! [4]
I agree with you very much. I would say for enterprise use where cost/efficiency is not a factor, Xen has an edge over VZ. However for a service provider or other situation where CPU/RAM/DISK resources are shared among environments to ensure profitability/efficiency, openvz is far superior. Also, VZ is much simpler to use, and all of the command line utilities are well documented. [5]
Last week when we were in limbo about what to do, it was decided to try out XEN Virtualization. From what is written in the press the Xen system has alot of promise, Features such as opensource with live migration and backups sounds great; but was far too complicated to get working in our configuration. OpenVZ was the only virtual server system that was simple to install and get working. [6]
It still amazes me how well OpenVZ works. [7]
[03:30:15] <pookey> well, I've been using openvz for all of about an hour, and I'm pretty impressed so far :)

I am playing around for years with all major virtualization environments like all VMware products, Microsoft and several xen based solutions. But OpenVZ is the overall winner. [8]
I messed around with VMWare and Xen. I found VMWare to be somewhat over kill and Xen was damned hard to get working. The user community on the Xen mailing list is rather hostile. It looked like A number of people hang out there for the sole purpose of flaming the clueless.
I've found the OpenVZ folks to be very helpful and knowledgeable. OpenVZ is simple to install and get running. It pretty much satisfies my needs. [9]
I'm a sysadm and have always used xen/qemu/virtualbox/vmware server for my VMs and my customer's ones. Yesterday I decided to give OpenVZ a try and... I'm amazed. It's fast, easy and reliable.Live migration works like a charm and the use of rsync assures low data transfers. Great. [10] Stefano Marinelli [11]
OpenVZ is one of the few pieces of software that I truly love. It works wonderfully. It should become part of the mainline kernel. Nick Andrew [12]
And thanks again for OpenVZ. Our business couldn't do what we do, as well as we do, with VMWare or Xen. Gregor Mosheh, System Administrator, HostGIS cartographic development & hosting services.
