Weird indeed. Well, RHEL 7.2 is out for more than a month and there is centos 7.2 beta and perhaps rc as well, it's due very soon Sandro, we should think about it - since we push qemu-kvm-ev we do not really enforce anyone to run on el7.2. We want to do that for various reasons as soon as possible. Maybe updating qemu-kvm-ev to require new 7.2 libvirt? >> >>>> 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] >>>>>>>> http://lists.ovirt.org/mailman/listinfo/users >>>>>>> _______________________________________________ >>>>>>> Users mailing list >>>>>>> [email protected] >>>>>>> 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] >>> >>> -- >>> 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] > > -- > 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]
