Subject: [PATCH] Workaround segfault when qemu-kvm runs inside a VM (RHBZ#516543).

Regression was introduced by this commit:

http://git.kernel.org/?p=virt/kvm/qemu-kvm.git;a=commitdiff;h=b8083e930efc1ee85a7ad7e700dbd0f52ebb32dd

Upstream discussion:

http://www.mail-archive.com/kvm@vger.kernel.org/msg19890.html

Note: NOT UPSTREAM and this is something of a hack.  Upstream are

still debating how they really want to fix this.
