Copying xen-devel and some relevant maintainers, start of thread is http://lists.xen.org/archives/html/xen-users/2015-12/msg00073.html From that, this is Xen 4.5.1 on arch Linux. Andre, could you take a look under /var/log/xen for logs relating to a domain to which this has happened, in particular the qemu log. It would also be useful to see the corresponding guest cfg file I expect.
