Comment # 6 on bug 913515 from Ji���� Krautwurm

Hello Josef,
please tell me what exactely you need, i.e. what should I do to gather it.
Appologize, I have rather basic opensuse knowledge only, same for Bugzilla
(wrote the answer already and would like to attache the file, but the answer
text gone!?).

Basicaly I would like to test Xen virtualization on opensuse 13.2. After fresh
installation Bootloader module was fine, but I was unable to setup VM guest.
I posted this to opensuse forum - by the way: 
https://forums.opensuse.org/showthread.php/504096-Xen-opensuse-13-2-unable-to-install-vm-guest-quot-End-of-file-while-reading-data-Input-output-error-quot

Then I added VirtualBox, which works fine, and after that I would like to
change bootloader preference to desktop kernel. Dont know exactely when it
appears, but after manipulation with VirtualBox it is no more possible to open
Bootloader module with described ERROR. Both Xen and VirtualBox setting I did
with GUI wizards, I did not changed storage configuration intentionaly.

If I understand Your last message well, I should attach all y2logs and some
libzypp. I have y2log-x.gz x=1-7 and where is libzypp ?
I will add all y2log-x briefly.
