[ovirt-users] Some questions

It depends on the supportedENGINEs which getVdsCaps will return.
Generally, VDSM for 3.x should keep supporting its 3.x previous minor versions.

hi,

my concern is that we have some critical MV. If the node enters into non
-operational state after upgrading the engine. Will be machines up?

I've been searching and upgrading should be progressive, 3.0 to 3.1, 3.1 to
3.2 ....
I guess if the nodes VDSM update to the latest version, and later I'll update
the engine version by version nodes wouldnt enter on non-operational state
and not suffer any court in MV. Am I right?

Thank you very much for your help
