[Pkg-xen-devel] Bug#798510: xen-utils-common: xendomains domU auto-starting fails after upgrade to Debian 8

[Wolfgang Karall-Ahlborn]

Package: xen-utils-common
Version: 4.4.1-9+deb8u1
Severity: important

Dear Maintainer,

After upgrading to Debian 8, auto-starting of domUs via /etc/xen/auto
fails with errors like this

Sep 09 09:29:21 host xendomains[948]: Starting Xen domain domU (from /etc/xen/auto/domU.cfg)...failed.
Sep 09 09:29:21 host xendomains[948]: libxl: error: libxl_exec.c:129:libxl_report_child_exitstatus: /etc/xen/scripts/block add [-1] died due to fatal signal Killed
Sep 09 09:29:21 host xendomains[948]: libxl: error: libxl_exec.c:129:libxl_report_child_exitstatus: /etc/xen/scripts/block add [-1] died due to fatal signal Killed
Sep 09 09:29:21 host xendomains[948]: libxl: error: libxl_exec.c:129:libxl_report_child_exitstatus: /etc/xen/scripts/block add [-1] died due to fatal signal Killed
Sep 09 09:29:21 host xendomains[948]: libxl: error: libxl_create.c:1054:domcreate_launch_dm: unable to add disk devices

Services seem to get started in the correct order according to LSB
headers in the init scripts:

Sep  9 09:28:49 host systemd[1]: Starting LSB: Xen daemons...
Sep  9 09:28:49 host xenstored: Checking store ...
Sep  9 09:28:49 host xenstored: Checking store complete.
Sep  9 09:28:49 host xen[880]: Starting Xen daemons: xenfs xenstored xenconsoled init-dom0.
Sep  9 09:28:49 host systemd[1]: Started LSB: Xen daemons.
Sep  9 09:28:49 host systemd[1]: Starting LSB: Start/stop secondary xen domains...

Inserting a 'sleep 10' into /etc/defaults/xendomains solves the issue,
so it seems to be some timing problem.

Cheers
Wolfgang
