Pkg xen devel - Feb 2014 - Bug#737613: xen-hypervisor-4.3-amd: Xen not loading dom0 on Jessie - FATAL error on running /etc/init.d/xen

Package: xen-hypervisor-4.3-amd64
Version: 4.3.0-3+b1
Severity: critical
File: xen-hypervisor-4.3-amd
Justification: breaks the whole system

Dear Maintainer,
Installation is a minimal system designed only to get dom0 working.

The following are the uncommented GRUB commands


GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX=""
GRUB_GFXMODE=640x480
GRUB_CMDLINE_XEN="dom0_mem=2048M dom0_max_vcpus=1 dom0_vcus_pin"

The following are the uncommented contents of /etc/xen/xend-config.sxp

(vif-script vif-bridge)
(dom0-min-mem 1024)
(enable-dom0-ballooning no)
(total_available_memory 0) 
(dom0-cpus 1)
(vncpasswd '')

All other configuration as per install. (except networking)

After selecting the hypervisor in grub, the hypervisor seems to load OK and then
loads dom0.
As the init scripts are run the boot fails with the error

FATAL: Failed to initialize dom0 state: iappropriate ioctl for device.

and the system freezes.

When the line

xenstore-write "/local....

in the function xenstored-start in /etc/init.d/xen is commented out the error
goes away.

Inserting a mount>foo command immediately before this call shows the
following

sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime)
proc on /proc type proc (rw,nosuid,nodev,noexec,relatime)
udev on /dev type devtmpfs (rw,relatime,size=10240k,nr_inodes=217982,mode=755)
devpts on /dev/pts type devpts
(rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000)
tmpfs on /run type tmpfs (rw,nosuid,noexec,relatime,size=175516k,mode=755)
/dev/disk/by-uuid/b5504546-ca42-4544-8bdb-442aa2b3ee0a on / type ext4
(rw,relatime,errors=remount-ro,data=ordered)
tmpfs on /run/lock type tmpfs (rw,nosuid,nodev,noexec,relatime,size=5120k)
tmpfs on /run/shm type tmpfs (rw,nosuid,nodev,noexec,relatime,size=351020k)
/dev/sda1 on /boot type ext3 (rw,relatime,stripe=4,data=ordered)
rpc_pipefs on /run/rpc_pipefs type rpc_pipefs (rw,relatime)
xenfs on /proc/xen type xenfs (rw,relatime)

Hope all that is sufficient.

IME this is usually down to a mismatch between the dom0 userspace tools
and the hypervisor, but if this is a fresh system then I see no reason
for that to be the case. Please can you check that all of your xen
related packages are from the same version though.

So the error is from the xenstore-write and not the launch of the
xenstored daemon just prior to it? How strange, not what I expected.

Please could you also provide the output of:
      * lsmod
      * ls -l /dev/xen
      * cat /proc/misc
      * ls -l /var/run/xenstored
      * ls -l /var/lib/xenstored

Please can you also confirm with ps whether or not xenstored is running
and whether there are any xenstored messages anywhere under /var/log
(daemon.log being the most likely candidate)

If xenstored is not running please could you do
	strace -o /tmp/xenstored -fff xenstored 
and send us /tmp/xenstored.* (and recheck the logs for messages)

Once/if xenstored is running the please:
	strace -o /tmp/xenstore-write -fff xenstore-write /local
and send us /tmp/xenstore-write.*

Thanks,
Ian.
