I am facing the similar problem, although I was not able to create new virtual guests neither with "xl" nor "virsh". In the Opensuse Forum -> Virtualization I added the thread Xen opensuse 13.2 unable to install vm guest "End of file while reading data Input/output error" 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 where my attempts I made so far are described. I am ready to provide necessary log outputs, If I will be asked to. If I could help, please describe in beginners level what to do to collect the info. Please help with the fix.
