From 1864b94abb20fec2fbc4b99c764bc427141d79f0 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Thu, 14 Jul 2011 11:52:08 +0200 Subject: [PATCH] s390x: implement SIGP restart and shutdown An s390x OS does reboot and shutdown triggers through hypercalls that we didn't implement on the TCG backend yet. That means that so far we couldn't shut down virtual machines for example, having them hang on shutdown when not using KVM. With this patch, this restriction is gone. We can now shut down and reboot s390x virtual machines even when using the TCG backend.
