Ooooh I like that one!
The thread got a little confusing --
Are we talking about using NTP as a client on VMs?
Or using VMs to run NTP servers?
If as a server:
Hell NAH! Don't do it. Like everyone said, the clock available to the
OS isn't reliable, you don't want its drift to affect other machine's
clocks.
If as a client:
Hell YAH! VM clocks are unreliable. Heck, we had a dedicated server that
had a 14 second a day drift! We used the heck out of NTP to keep that
sucker from losing time.
Sort of related: I really love OVH as a hosting provider, but they offer
one time source, and it is in Beauharnois, Canada, even if you use their
Oregon US Datacenter. These NTP devices are so inexpensive to cover a whole
datacenter, why are we introducing network latency?!?
I am of the opinion that each physical datacenter should provide its own
Stratum 1 NTP source.

How many NTP servers do you guys run?
I just spun up two NTP servers in different locations on this network.
Metaswitch just asked me for at least four (preferably five, or even more).
Right now, the ones I have are just referencing the US pool. Eventually,
they'll reference on-net GPS-backed devices.

LeoNTP server. If you want to run your own.
