I reckon any testing you do should use the same Distribution & Asterisk
config on VM AND Bare metal.
if you feel you need to use Astlinux in the VM, then use it also on bare
metal.
go from there... otherwise your comparing apples with oranges..
too many potential differences to even consider it being asterisk.
also if your going to test it might I suggest using VMWare Server or ESXi
