Re: [Xen-devel] Debian kernel 3.1 onwards fails to boot on Xen domU

[Deepti kulkarni <deepti.kdeeps@xxxxxxxxx>]

On a PV, the vm doesn't boot and I see error "Error: Starting VM - Traceback (most recent call last): - File "/usr/bin/pygrub", line 808, in ? - fs = fsimage.open(file, part_offs[0], bootfsoptions) - IOError: [Errno 95] Operation not supported"

There are several suggested workarounds and diagnostics to try in that
bug log -- have you tried them?

That said I'm not necessarily convinced your issue is related to that
bug, which was quite PVHVM specific (yet you mention having the problem
on PV too).

If none of the suggested workarounds help then I would suggest making a
full bug report (with logs etc) as described in
http://wiki.xen.org/wiki/Reporting_Bugs_against_Xen

In particular full guest logs and a description of the installation
method which you used would be useful.

Ian.
