Looking at the log and Linux 4.17, none of the PV drivers seem to have
suspend/resume callback. This might be the reason of the crash as from
Xen PoV this is a new guest so the memory and event channel have not
been configured. The guest should really do it again.
It looks like there are some code in drivers/xen/manage.c to handle
suspend request from the toolstack. I am not entirely sure why we need
our own way to suspend and not re-used the Linux one.
Jurgen, Boris, do you know if suspend-to-disk from the guest console
works on x86?
It looks like it was not supported. Amazon recently sent an RFC to
support it (see [1]). This seems to have some architecture specific code
but only for x86. Arm bits would need to be implemented.
Cheers,
