[Freeswitch-users] Virtualisation and freeswitch

Hello list, le me introduce myself first, I am Grigoriy Dobrovolskyy currently working as voip administrator and call centeres integrator. I worked a lot with asterisk, i think Fs is a great software but not easy to learn. I have googled my question and did not found a clear answer. With what technology i can virtualise freeswitch without timer problems ? I know that i can use OpenVZ but it's more 'jail' then virtualisation. I heard that Amazon EC with High CPU instance works (confirm?) Can someone give me info of a succesfull installations with Conferences, Moh / mixing ? And a technology used ? Thank you.
