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

[Steve Hnizdur]

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.
