Does anyone have any perspective on how well Asterisk performs and scales inside a Xen hypervisor environment?
I tried on many different pieces of hardware with various recent Xen versions and it always had some level of unpredictability and was not as reliable as running on bare hardware. I wouldn't do it for production but it was fine for testing (sort of :>).
All other things being equal, certainly the bare HW will win out. I'd like to also note that Xen provides a mechanism to dedicate a CPU core to a virtual machine in a system appropriately equipped. Might be useful. As to whether all critical sources of contention can be controlled adequately to achieve an equivalent or sufficiently robust environmentfor Asterisk -- I can't say authoritatively. It's reasonable to think it might be possible.
