All oVirt VMs, from libvirt's POV, are "transient". Their xml is generated on-the-fly from data in the engine's database. You definitely need the database and the engine. Make sure you back them up often, make sure you have means to restore if needed, test these means often. We recently introduced new functionality 'hosted-engine --restore-from-file', which should spare you from many of the previously-manual steps needed for restore: https://bugzilla.redhat.com/show_bug.cgi?id=1469908 If you feel like this is still not enough for your needs, perhaps hosted-engine is not for you. Although hosted-engine is very popular these days (IIRC more than 50% of the setups are hosted-engine), some people do maintain for their engine two separate physical machines with copies of the engine and some cluster software to run it on them in HA. In the past there were also discussions about native support for redundancy (e.g. allow running more than one engine against a single db (replicated, perhaps, using PostgreSQL means)), but it was decided this is too complex and not important enough. > > Thanks > > > On Tue, Feb 12, 2019 at 8:56 AM Petr Kotas <pko...@redhat.com> wrote: >> >> Hi Hetz, >> >> with oVirt, the virtual machines that does not run are not present on the >> node.
