So obviously you need to add ntp-service if you just use %base-services
+ some minor additions.... I thought it was part of base. This fixes the
resolution of names, but introduces problems with ntpd (unexpected
origin timestamps).
I still can't ping, but I will let the VM run for a while now to see if
something needs to get in sync.
