I have some more info on this second problem, the first problem is 
clearly the same as described in this patch/workaround: 
http://xenbits.xenproject.org/gitweb/?p=xen.git;a=commit;h=d513814db6af2b298b8776d7ffc5fb1261e176f4

Now the system will come back up on reboot, but not if I upgrade the 
kernel on the guest (I can upgrade everything else).

Any ideas? it is either that there is some new incompatibility 
between kernel 3.11.10 and 3.12.8 on f20, or pygrub on centos5 can't 
cope with two kernel entries.
