Hi Martins, Have you unmanaged your xen cluster from cloudstack UI before xen upgrade? This is a mandatory step that disconnects all xen servers in the cluster from while upgrade is going on.
You can go through http://www.shapeblue.com/how-to-upgrade-an-apache-cloudstack-citrix-xenserver-cluster/ KB article that explains xen cluster upgrade in cloudstack.
