Not sure if you doing right thing. Updating some packages (LVM is most 
well known) will break XCP in subtle way (f.e. no more disk resizes 
after lvm update on master and possible disk data corruption after 
updating on slaves).
Hypervisor and kernel should NEVER be updated from vanilla centos, they 
are very different.
We usually unpack Citrix updates to XenServer and install 
hypervisor/kernel from those updates.
