Is: Xen 4.2 and using ''xl'' to save/restore is buggy with PVHVM Linux guests (v3.10 and v3.11 and presumarily earlier as well). Works with Xen 4.3 and Xen 4.4. Was:Re: FAILURE 3.11.0-rc7upstream(x86_64) 3.11.0-rc7upstream(i386)\: 2013-08-26 (tst001)
Hey,
I have a nighly build/test system that boots various machines with
upstream Linux and randomly selects Xen 4.1, Xen 4.2, Xen 4.3 and unstable.
After a bit of digging I found out that Xen 4.2 ''xl'' (but not
''xm'')
has some badness in it. When "migrating" (''xl'' save
followed by ''xl'' restore'')
the PVHVM guests (and only PVHVM) end up dying. The best theory I came up
with is that they don''t have the shared_info setup correctly as the
guest
is not receiving any events.
This happens with both 32 and 64 bit guests. It happens also with
v3.10.
Here is a output from the of the guest using "console=hvc0" where you
can
see it starting, and being saved and restored. And then dying as it
can''t read anything:

Once more I need to stress that it works great when using ''xm''
in Xen 4.2
but fails over when using ''xl'' in Xen 4.2.
I can''t recall whether ''xl'' in Xen 4.2 was considered
experiemental or
production ready at that point?
Thoughts? Ideas? Saw this in the past and you know the answer?

This works in 4.3, though? Maybe there was a fix that didn''t get backported? Ian J, do we test PVHVM suspend/resume in osstest? -George

Yes, I think so (assuming RHEL6 does PVHVM).

Should later RHEL6 versions be added aswell? 6.4 is the latest.. (with a lot of kernel changes/patches). -- Pasi

Maybe there was a fix that didn''t get backported?Yes, it does work there. And I also make sure to use the same version of QEMU in both places - the traditional one. Not that it would make a big difference.> > Ian J, do we test PVHVM suspend/resume in osstest?.. Using the traditional or the the SeaBIOS?> > -George
