If you are on x86_64 you shouldn't see any Xen specific proiblems with
doing upgrades. i386 is a little more complicated though because we switched
from non-PAE to PAE in the Xen kernels - so if you were to upgrade your
host without first preparing your guests you'll be unable to boot the guests
after the upgrade. 

The solution is fairly simple though - the latest FC5 errata also provides a 
'kernel-xen' RPM which is PAE enabled. So before upgrading your host, just 
make sure you have done 'yum install kernel-xen' in each of your guests.
This will let your FC5 guests contonue working on an FC6 host - you can then
upgrade your guests to FC6 at will.
