ok..and just for the sake of completeness - what is libvirt version exactly? If you’re running <1.2.14 then your initial comment make a lot of sense…. Yes, el7.2 has the right one (1.2.17) but even on 7.1 it should support it and if it doesn’t it’s our problem we should fix in ovirt (similarly as we solve qemu by shipping it ourselves) >> Or how/when did you create it? > those vms have been created before uprading to 3.6, some of them from a blank > template, other one based on a el7 template. >> >> Thanks, >> michal >> >>> >>> I tried to restart vdsmd but it is the same, even on other hosts. >>> >>> any help will be appreciated, thank you. >>>> >>>>> >>>>> Thank you for your help >>>>> _______________________________________________ >>>>> Users mailing list >>>>> [email protected] <mailto:[email protected]> >>>>> http://lists.ovirt.org/mailman/listinfo/users >>>>> <http://lists.ovirt.org/mailman/listinfo/users> >>>>> >>>>> _______________________________________________ >>>>> Users mailing list >>>>> [email protected] <mailto:[email protected]> >>>>> http://lists.ovirt.org/mailman/listinfo/users >>>>> <http://lists.ovirt.org/mailman/listinfo/users> >>> >>> -- >>> Nathanaël Blanchet >>> >>> Supervision réseau >>> Pôle Infrastrutures Informatiques >>> 227 avenue Professeur-Jean-Louis-Viala >>> 34193 MONTPELLIER CEDEX 5 >>> Tél. 33 (0)4 67 54 84 55 >>> Fax 33 (0)4 67 54 84 14 >>> [email protected] <mailto:[email protected]> >> > > -- > Nathanaël Blanchet > > Supervision réseau > Pôle Infrastrutures Informatiques > 227 avenue Professeur-Jean-Louis-Viala > 34193 MONTPELLIER CEDEX 5 > Tél. 33 (0)4 67 54 84 55 > Fax 33 (0)4 67 54 84 14 > [email protected] <mailto:[email protected]>
