Subject: [Qemu-devel] [PATCH 7/7] remove smp restriction from kvm
Date: Thu, 26 Nov 2009 15:25:00 -0200	[thread overview]
Message-ID: <1259256300-23937-8-git-send-email-glommer@redhat.com> (raw)
In-Reply-To: <1259256300-23937-7-git-send-email-glommer@redhat.com>

We don't support smp without irqchip in kernel, so only abort in
that situation
