Hi


I would like the opinion of you and if anyone has a similar scenario. I
have a project for installation of a Asterisk server in a client with
about 400 extensions. My question is whether this scenario carry an
Asterisk virtualized. Will be used only extensions and trunks sip sip, 1
queue with 2 agents, without call recording. It is best to use XEN or
VMware? Which best version of Asterisk for this scenario?

Use XEN in paravirtualized mode: NOT hardware/full virtualized!

Even when using specialized drivers, you get a considerable performance
hit. When virtualizing Linux, hw-virtualization is an unneeded waste of
cpu-cycles. Acceptable for windows clients, not otherwise.
