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 grub-xen-host - GRand Unified Bootloader, version 2 (Xen host version) i A libxen-4.6 - Public libs for Xen i A libxenstore3.0 - Xenstore communications library for Xen i A xen-hypervisor-4.6-amd64 - Xen Hypervisor on AMD64 i A xen-linux-system-4.6.0-1-amd64 - Xen system with Linux 4.6 on 64-bit PCs (meta-package) i xen-linux-system-amd64 - Xen system with Linux for 64-bit PCs (meta-package) i A xen-system-amd64 - Xen System on AMD64 (meta-package) i A xen-utils-4.6 - XEN administrative tools i A xen-utils-common - Xen administrative tools - common files 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.
