Description of problem:
  Guest with running spice-vdagent will be killed if connect it through virt-viewer for 2nd time.

spice-protocol-0.12.2-1.el6.noarch
spice-glib-0.14-5.el6.x86_64

spice-gtk-python-0.14-5.el6.x86_64
spice-gtk-0.14-5.el6.x86_64

libvirt-client-0.10.2-5.el6.x86_64
libvirt-python-0.10.2-5.el6.x86_64

Reproduce steps:
1. Install a RHEL6.3 guest with gnome.
2. Make sure guest has spice+qxl graphic devices and spicevmc channel exists.
3. Start the guest and make sure spice-vdagentd service is running in guest.
4. Run virt-viewer $guestname.
5. Change the size of console form for several times to make spice-vdagent change the resolution in guest, about 3-5.
6. Close virt-viewer and connect to the guest again.

Actual results:
1. After step 6, guest was killed.

Expected results:
1. After step 6, guest should keep alive.

We really need the logfile from QEMU /var/log/libvirt/qemu/$GUESTNAME.log after the guest has crashed.

Looks like either QEMU or spice-server are hitting an assertion, causing QEMU to abort. Moving to QEMU since it isn't virt-viewer's fault.

We hit many similar issues these days after upgrade the spice-server. Adding spice guys to have a look at this issue.

Hi, Uri and Yonit
Could you guys help have a look at this issue if it's related spice-server? 

Two similar bugs:

Thanks,

Comment 9 Uri Lublin 2012-11-28 14:45:01 UTC 
How easy/hard is it to reproduce ?

It's not easily reproduced for me.

On my RHEL-6 host/client:
   qemu-kvm-0.12.1.2-2.334.el6.x86_64
   virt-viewer-0.5.2-16.el6.x86_64

On my RHEL-6.3 VM:
   spice-vdagent-0.8.1-3.el6.x86_64
   kernel-2.6.32-279.el6.x86_64


Can you please try spice-server-0.12.0-5 ?
The fix in 0.12.0-3 is related to monitors_config.
