Package: xen-hypervisor-4.6-amd64
Version: 4.6.0-1+nmu2
Severity: grave
Justification: renders package unusable

I installed the xen-linux-system package on my system (Asus ZenBook UX305CA-FC022T) 
running Debian Sid with KDE as desribed on https://wiki.debian.org/Xen.
That in turn installed the following package with 'xen' in their names:
$ aptitude search ~ixen
i A grub-xen-bin                    - GRand Unified Bootloader, version 2 (Xen binaries)

i A xenstore-utils                  - Xenstore command line utilities for Xen

I didn't prioritise Xen over Native as I first wanted to get familiar with Xen 
(this is the first I tried Xen and also my first experience with EFI).
I then rebooted and tried 2 different Xen items from GRUB:
=== Debian GNU/Linux, with Xen hypervisor ==============================

Loading Xen 4.6-amd64
WARNING: no console will be available to OS
Loading Linux 4.6.0-1-amd64 ...
Loading initial ramdisk ...

(hangs)

=== Advanced options for Debian GNU/Linux (with Xen hypervisor) ========
=== Xen hypervisor, version 4.6-amd64.efi ==============================
=== Debian GNU/Linux, with Xen 4.6-amd64.efi and Linux 4.6.0-1-amd64 ===

Loading Xen 4.6-amd64.efi ...
error: invalid arch-dependent ELF magic.
Loading Linux 4.6.0-1-amd64 ...
error: you need to load the kernel first.
Loading initial ramdisk ...
error: you need to load the kernel first.

Press any key to continue ...

(any key returns to the GRUB menu)
========================================================================

where the text between "===" denotes the GRUB menu items I choose.

I will attach the grub.cfg file later on. One thing that strikes me as odd in it is the 
literal text 'placeholder' in it. It may not be a problem and intended, I don't know.

Using the procedure as described in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=820807 
I was able to boot into Xen, where I changed the kernel and ramdisk to match my (current) 
kernel and upped dom0_mem to 2048M as it booted my KDE system extremely slow with 512M.
For the root=UUID= part I used the UUID of the device which holds my current system.
The procedure is also described in http://wiki.xenproject.org/wiki/Xen_EFI
This bug report should have the output of  'dmesg', 'xl info' and 'xl dmesg' attached and 
if not, I'll send them once I get a bug number back.

Many thanks to #xen on freenode for helping me getting it to boot and (hopefully) help me 
get the relevant info for a proper bug report.


There are a number of things that worry me about the state of Xen package(s) on Sid/testing 
though which I feel should be pointed out, next to this bug report:
- The last 2 uploads were NMU and I haven't seen much (if any) response to other bug reports 
and/or on the package(s) maiing list.
- Apparently the xen build in Sid is obsolete and there have apparently been 300 patches 
since and the latest 4.6 release is now 4.6.3.
- Before adding another RC bug (this one), there were already 7 RC bugs, including one about 
multiple security issues. For some odd reason it's still not marked for auto-removal. 
IMO this package is absolutely not fitted for Stretch in its current shape and that's besides 
the reason for this bug report, although I also expect Xen to work on a SandyBridge system 
with EFI in Stretch.


Hopefully Xen will get back in shape soon.
If you need more info, I'll do my best to provide it.

Cheers,
  Diederik
