That's the case here, running on bullseye/testing.

x86_64 host here, and some old 32 bit virtual machines, no weird
network or hardware pass through setup, rather simple.  HVM and pvgrub
based DomU VMs run fine so far.  pygrub based VMs, both 32 bit and 64
bit fail with the following error:

  Traceback (most recent call last):
    File "/usr/lib/xen-4.14/bin/pygrub", line 27, in <module>
      import xenfsimage
  ModuleNotFoundError: No module named 'xenfsimage'

Joined that for now.

Should I file a new bug for the above mentioned problem?  Or is that
covered by #975062 already?

Ok, so you're running Debian testing, and our Xen 4.14 package migrated
into there, and Debian testing has python 3.8 as python3-defaults:

https://packages.debian.org/src:python3-defaults

Exact hits
Source Package python3-defaults

    jessie (python): 3.4.2-2
    Binary packages: [show 16 binary packages]
    stretch (python): 3.5.3-1
    Binary packages: [show 16 binary packages]
    buster (python): 3.7.3-1
    Binary packages: [show 18 binary packages]
    bullseye (python): 3.8.6-1
    Binary packages: [show 18 binary packages]
    sid (python): 3.9.0-3
    Binary packages: [show 18 binary packages]

And what do we have in the packages that just migrated to testing:

xenfsimage.cpython-39-x86_64-linux-gnu.so

So, apparently there's some thing that causes xenfsimage to end up with
such a monstrous name, and if you have python 3.9 as default (in
unstable) it will find it, and for testing with 3.8, it will not.

I have no idea what's going on here. We probably should find out.

It should be a different issue yes.

Hello,

FTR, we found what seems to be the problem in IRC yesterday, see
below.

Testing has python 3.8 as default at the moment, while unstable
already has 3.9.  The file packaged for testing however is
'xenfsimage.cpython-39-x86_64-linux-gnu.so' but that seems to be for
python 3.9, not for 3.8.  When starting pygrub manually with python3.9
that error goes away, but I suppose that would not work from within
the xen config, or does it?
