Re: [ovirt-users] Changing Cluster CPU Type in a single Host with Hosted Engine environment

Hi Thanks a lot for you help. Just to be sure. The Database would be the Datebase on the HostedEngine right ?

After this operation should it work directly or is a restart required ?

And for the Bug report this should be done here https://bugzilla.redhat.com/enter_bug.cgi?classification=oVirt ?
