You can set the CPU level through the SDK, after you add the host (didn't check that, but see no reason it won't work). > > > > >> > >>> Thanks, > >>> michal > >>> > >>>> > >>>> Michael, can you take a look at http://gerrit.ovirt.org/22129 and > >>>> advise? > >>>> > >>>> > >>>> -- > >>>> Sandro Bonazzola > >>>> Better technology.
