After installing openSUSE 13.2 on UEFI-capable system and adding Xen hypervisor
to it there is no possibility to boot Xen/Domain 0: system freezes completely
(i.e, cursor on console doesn't blink).
Experimenting has shown that module that causes such a freeze is efivarfs.ko.
Adding to /etc/modprobe.d/99-local.conf the following line:

blacklist efivarfs

eliminates problem.
