Hi Daniel,
here's from my personal experience: Our setup at ng-voice is a little weird sometimes: We've rented some virtual servers at a german provider (who uses Xen). On these virtual servers we've installed OpenVz, which for us is absolutely great, if you are just working with Linux-Servers. While Xen is a rather complete virtualization, OpenVz is lightweight and comes in handy, if you just want to logically separate servers. We've got each IMS component (P-/I-/S-CSCF, HSS, Application-Servers, Databases) running on a dedicated OpenVz Container, which is really great. We've even got a CentOs-Container running on a Debian OpenVz, which is started "on-demand" in order to build RPM-Packages. With OpenVz you can even move Containers from one host to another, theoretically with zero downtime (doesn't work with SEMS, don't know about other software). For our IMS-setup, we work with RTP-Relaying, which works great within virtualization, i cannot complain.
At another customer (a fibre provider in Germany), we're running all the infrastructure on Xen-only. An infrastructure provider takes care of the administration, but those servers run poorly (RTP-Relaying is okay but everything else is really slow).
Conclusion for me: VoIP on virtual servers can work great, but the virtualization infrastructure needs to be administered properly which may not be an easy task, if you are new in this subject.
Kind regards, Carsten

Hello,
just asking to see your experience deploying sip platforms on virtual systems. So far I was running Kamailio in virtual machines and no problems, but I insisted that media servers to be on physical machines. Lately is more pressure from the market to go everything virtual.
So the question is more about having everything on virtual systems, proxy and media server, where the media server can deal with transcoding, conference rooms and IVRs.
Any strong comments pro or against?
What is your preferred virtualization system for such deployments?
Cheers, Daniel
