Hi Chris, This is a known issue in the console code that was introduced by commit: commit 4716138229ae47c5492c13a8622b779889560fd7 Author: Peter Krempa <pkrempa> 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. in libvirt 0.9.11. The problem was later fixed by commit: commit 45edefc7a7bcbec988f54331ff37fc32e4bc2718 Author: Peter Krempa <pkrempa> Date: Fri Aug 3 11:20:29 2012 +0200 conf: Remove console stream callback only when freeing console helper Commit ba226d334acbc49f6751b430e0c4e00f69eef6bf tried to fix crash of the daemon when a domain with an open console was destroyed. The fix was wrong as it tried to remove the callback also when the stream was aborted, where at that point the fd stream driver was already freed and removed. This commit is included in the libvirt-0.10.0 upstream release. Please upgrade at to least this version or let the maintainer of your distro include the patches pointed out in the downstream release.
