From 61bde82caee95426bf1ad53fefc8dc691b8ba37c Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Mon, 11 Jun 2012 16:06:57 +0200 Subject: KVM: s390: Set CPU in stopped state on initial cpu reset The initial cpu reset sets the cpu in the stopped state. Several places check for the cpu state (e.g. sigp set prefix) and not setting the STOPPED state triggered errors with newer guest kernels after reboot.
