File kvm-qemu-preXX-kvm-Mark-VCPU-state-dirty-on-creation.patch of Package kvm.openSUSE_11.4_Update
From d841b6c4f16c3fc7afe2ce355e7e42813345f053 Mon Sep 17 00:00:00 2001 From: Jan Kiszka <jan.kiszka@siemens.com> Date: Tue, 15 Mar 2011 12:26:20 +0100 Subject: [PATCH] kvm: Mark VCPU state dirty on creation This avoids that early cpu_synchronize_state calls try to retrieve an uninitialized state from the kernel. That even causes a deadlock if io-thread is enabled.
