File kvm-qemu-preXX-qemu-kvm-Mark-VCPU-state-dirty-on-creation.patch of Package kvm.853
From f4de8c1451f2265148ff4d895a27e21c0a8788aa Mon Sep 17 00:00:00 2001 From: Jan Kiszka <jan.kiszka@siemens.com> Date: Mon, 21 Feb 2011 12:28:07 +0100 Subject: [PATCH] qemu-kvm: Mark VCPU state dirty on creation This avoids that early cpu_synchronize_state calls try to retrieve an uninitialized state from the kernel, which even causes a deadlock.
