Is there any way to get a virtual guest to only query it's current host for NTP?
I'm not talking about configuring ntp.conf with the host's IP here either as VLAN's & firewalls may block that traffic. Also migration to a different host would require ntp reconfig & restart. A direct (intercepted?) query from the guest to the host.
I've tried various NTP solutions and it seems to me (theoretically) that it might be best for a guest to query only it's current host for an NTP sync (notwithstanding the VMware advice not to use their sync-with-host option).
It might/would require a version of NTP that is virt-aware.
Only one NTP source would be required as the guest wouldn't be running if the host wasn't available.
