Subject: [Qemu-devel] [PATCH 1/3] pseries: Increase maximum CPUs to 256
Date: Tue, 19 Apr 2011 11:54:50 +1000 [thread overview]
Message-ID: <1303178092-29891-2-git-send-email-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <1303178092-29891-1-git-send-email-david@gibson.dropbear.id.au>
From: Anton Blanchard <anton@au1.ibm.com>
The original pSeries machine was limited to 32 CPUs, more or less
arbitrarily. Particularly when we get SMT KVM guests it will be
pretty easy to exceed this. Therefore, raise the max number of CPUs
in a pseries machine guest to 256.
