[Qemu-devel] [PATCH 2.1 06/28] man: improve -numa doc

From: Paolo Bonzini
Subject: [Qemu-devel] [PATCH 2.1 06/28] man: improve -numa doc
Date: Tue, 4 Mar 2014 15:00:34 +0100

From: Luiz Capitulino <address@hidden>

The -numa option documentation in qemu's manpage lacks the command-line
options and some information regarding how it relates to options -m and
-smp. This commit fills in the missing text.

+Simulate a multi node NUMA system. If @samp{mem}
+and @samp{cpus} are omitted, resources are split equally. Also, note
+that the address@hidden option doesn't allocate any of the specified
+resources. That is, it just assigns existing resources to NUMA nodes. This
+means that one still has to use the @option{-m}, @option{-smp} options
+to respectively allocate RAM and vCPUs.
