[Freeswitch-users] Virtualized FreeSWITCH

[Brent Paddon]

I suspect you would be better off with some virtualization platform more
like OpenVZ ('containers' rather than VM's) - and probably without any
hardware
installed (ie SIP to SIP - leave the gateways to a different part of the
network).

We've run some Asterisk instances in Proxmox (
http://pve.proxmox.com/wiki/Main_Page) and while it's early days, it looks
pretty
promising.
