[Pkg-xen-devel] Bug#702046: xen-utils-4.0: PyGrub VM Boot fails after xen-utils 4.0.1-5.6 -> 4.0.1-5.7 Update

[Sebastian Melchior]

Package: xen-utils-4.0
Version: 4.0.1-5.7
Severity: important

After Upgrading to xen-utils 4.0.1-5.7 my pygrub Xen VMs won't boot. Running pygrub manually shows:

/usr/lib/xen-default/bin/pygrub --args=root="/dev/xvda ro" --output=/tmp/foo  /dev/vg0/vm-disk
Using <class 'grub.GrubConf.Grub2ConfigFile'> to parse /boot/grub/grub.cfg
WARNING:root:Unknown directive load_video
WARNING:root:Unknown directive terminal_output
WARNING:root:Unknown directive source
Traceback (most recent call last):
  File "/usr/lib/xen-default/bin/pygrub", line 705, in <module>
    output_directory, not_really)
NameError: name 'output_directory' is not defined

After replacing the new pygrub file with the one from the previous package everything works as expected.

I looked in the upstream source and this suggests that there should be a:
    output_directory = "/var/run/xend/boot"
    not_really = False
somewhere around L646
If i insert that, it also works as expected.
