Comment 6 for bug 1520979

This might be nice to have but I would not see any reason to rush this. Xen is not on the ISO images (and the whole Xen host/hypervisor parts are in universe which usually means a lower priority on being perfect) so this can be fixed later, still.

Also a critical bug imo needs to be one that causes data loss (even high would not be true as that would be service disruptions) and this is an issue which affects new installations only. And it is recoverable at least using the recovery option of the server ISO. Should also be possible by accessing the grub menu and switching to the non-xen boot but I admit I would not be quick enough to hit left-shift during that little time that the hidden grub default allows.

For those reasons I would lower the priority to medium and add a task to add something to the release notes.
