I've not tested all-in-one upgrade, just to be sure, save current iptables config and do a backup before starting the upgrade.

In practice the problem is due to the fact that it is an all-in-one installation and so it pulled in the virt-preview part for vdsm and related packages (qemu-kvm, seabioes, etc..).
How much is it risky to bypass the "yum distro-sync" step? Will the fedup part run itself the distro-sync command then, or is it only a sort of pre-check to verify consistency of packages?
In my case if fedup will retain the ovirt repos all should go ok, correct?
