incredible simple solution: after attaching a FC 19 host to a OVirt 
cluster the machine will boot a debug kernel

[root at colovn03 ~]# dmesg | grep debug | head -1
[    0.000000] Linux version 3.11.10-200.fc19.x86_64.debug

Fixed that with:

[root at colovn03 ~]# vi /etc/default/grub
[root at colovn03 ~]# grub2-mkconfig -o /boot/grub2/grub.cfg

Everything is back to normal. Should I file a BZ for that?
