Hi,

Still not tested it, but it should work. Also, there is a hint in the release notes too:

In both cases (Federation and HA) no support is needed from MySQL to create a clustered DB, so admins can forget about MySQL replication.

If database replication is not needed there is no reason sqlite to not work.

Best Regards,

Yes it should work. It is better not to mix both backends (servers in MySQL, servers in sqlite), although it should work as SQL commands generated by oned are compatible for both backends this has not been tested.

Cheers

Frontend HA with sqlite seems to work initially for me in a test setup: https://github.com/marcindulak/vagrant-opennebula-ha-tutorial-centos7
