Hi,
I am seeing an issue in libvirt-0.9.4-23.el6_2.7.x86_64.rpm where my
virsh console output for a domain gets garbled because I have
virt-manager running and it is also trying to access the serial device
for the guest domain. Basically there is concurrent serial access and
half the text ends up on one end while the rest ends up on the other
end.
Sounds like you are running into the issue that was fixed for 0.9.11
with this patch:
commit 4716138229ae47c5492c13a8622b779889560fd7
Author: Peter Krempa <pkrempa(a)redhat.com>
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.
