Sounds like you are running into the issue that was fixed for 0.9.11
with this patch:
commit 4716138229ae47c5492c13a8622b779889560fd7
Author: Peter Krempa <pkrempa@xxxxxxxxxx>
Date: Thu Oct 6 12:24:47 2011 +0200
qemu: Add ability to abort existing console while creating new one
This patch fixes console corruption, that happens if two concurrent
sessions are opened for a single console on a domain. Result of this
corruption was that each of the console streams recieved just a part
of the data written to the pipe so every console rendered unusable.
and which is already present in the RHEL 6.3 beta build of libvirt,
thanks to https://bugzilla.redhat.com/show_bug.cgi?id=729940.
