If there is no transcoding it could work assuming that this is not a
call center where all extensions would pretty much be "up and running"
all the time.
i.e this is a setup for a large office installation.
Assuming a recent XEON cpu and adequate RAM, main stumbling block is
usually network performance so you need a machine with good ethernet
chipset and linux driver.
Also you will need to twick the dahdi timing source or strange things
could start happening 
I've used KVM and XEN but presonaly i feel much more "comfortable" with
KVM
As for asterisk version i would recommend 1.8 which is LTS at this
point.
