[Spice-devel] guest sessions freeze

[Josh Restivo]

I've seen other mention of a similar problem over the past year but no
resolution is ever given. I have two qemu-spice hosts at two different
physical locations. When I connect to either of them from spicy or
Christophe's osx port of vinagre, I frequently experience loss of input
(keyboard/mouse). It is then necessary to disconnect/reconnect to regain
control of the session. The hosts are ubuntu precise, the guests are ubuntu
oneiric running vdagent (though the problem exists with or without
vdagent). spice-related packages are obtained from bderzhavets' usbredir38
repo.

Some more pertinent info:
qemu-x86_64 version 1.0 (Debian 1.0-2011.12-0ubuntu1), Copyright (c)

QEMU emulator version 1.0 (Debian 1.0-2011.12-0ubuntu1), Copyright (c)

host kernel: 3.2.0-10-generic (64-bit)
guest kernel: 3.0.0-14-server (64-bit)

Before I go turning on debugging for all of the various moving parts, is
there anything obvious that I might check or a specific cog to debug for
maximum effectiveness?

Also, here is the libvirt xml associated with one of the guests, if it
helps...
