So obviously, VM-specific features that were added in 4.2 won't be applicable to those VMs until they are restarted (and then their custom-compatibility version is cleared so their effective compability-level would change to 4.2). But even when some VMs are set with custom-compatibility-version, the cluster is upgraded and so it should be possible to upgrade the DC. > > Luca > > > > -- > "E' assurdo impiegare gli uomini di intelligenza eccellente per fare > calcoli che potrebbero essere affidati a chiunque se si usassero delle > macchine" > Gottfried Wilhelm von Leibnitz, Filosofo e Matematico (1646-1716) > > "Internet è la più grande biblioteca del mondo. > Ma il problema è che i libri sono tutti sparsi sul pavimento" > John Allen Paulos, Matematico (1945-vivente) > > Luca 'remix_tj' Lorenzetto, http://www.remixtj.net , < > lorenzetto.l...@gmail.com> > _______________________________________________ > Users mailing list > Users@ovirt.org > http://lists.ovirt.org/mailman/listinfo/users >
