Often happens that VMs do not do very good time keeping, so using a VM
as the central NTP server is not really advised, you should instead get
a good source for NTP external to the virtualized environment and you
that one  as the time source for your network.

Of course if your virtualization environment guarantees a good clock, go
for it.

The recommendation is in the spirit of avoiding issues in the common
case, that up to the time of the writing was not very good :)

Simo.
