Adding NTP Support
Feature necessity
KVM is very sensitive to time issues especially when migrating a VM between 2 hosts with a big time gap. In a large deployment we need to make sure that the time is synched on all the hosts in the setup.
Feture Description
The intent is to use the organization's NTP server to sync time on all the hosts in ovirt setup.
Assumptions
- Organizations will prefer using their own NTP server rather than install a new one for ovirt.
- The NTP server should be configured only once (during ovirt installation), and populated to all hosts through bootstrap and registration.
- Changing the NTP server after installation in not supported - and will require manuall steps to sync it to all the hosts in the setup.
What needs to be done
ovirt-setup
- Need to extract NTP server details from user during the installation
- The NTP config should be optional
- Need to update the ntp server in vdc_option table
- Need to configure the ovirt-server ntp to sync with the NTP server
DataBase
- need to add the NTP server configuration to the vdc_options table
Questions
- Should we support more than 1 NTP server ? Answer: NTP requires 2 server to work at all and recommends at least 3 NTP servers.
- Should we expose this config through the ovirt-config utility ?
