I am using linux4.4 as dom0 as well as domU.In domU, I have enabled hibenation related configs and I am trying suspend to disk.With xen 4.10, hibernation is done sucessfuly but resume crashes. It would have been nice to switch to a more recent Linux as well because I don't think anyone worked on suspend/resume 2 years ago. There are effort to support suspend/resume in Xen (and I guess guest) but I suspect some work is still missing in newer kernel. Although that would be a better start than a 2 years old kernel for the guest. I have used given config file for domU. name = "domU" kernel = "/ZI-uh1" memory = 200 vcpus = 1 cpus = 1 disk = [ 'phy:/rfs1.img,xvda,rw'] extra = 'no_console_suspend loglevel=8 console=hvc0 xenconsole=tty earlyprintk=xx en rw dhcp=off resume=/dev/xvda resume_offset=331776 root=/dev/xvda rootwait' The hibernate(domU console) and resume logs are shown as below: root@debian-jessie:~# swapon /swapfile.img swapon: /swapfile.img: insecure permissions 0644, 0600 suggested.

I would have at least expected a stack trace afterwards. Can you point me towards what could be the issue ? If any other information is needed then I can provide it to you. 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? Mirela, as you are working on suspend/resume. Have you looked at the guest side? If so, do you have any insights on the problem?
