Description Stanislav Graf 2012-03-05 15:53:46 UTC 
Description of problem:
I use graphical console + spice in my VM.
My virt-manager frequently hangs for approx. 10 minutes, and I cannot use my system. I'm able to go to text console (ctrl+alt+f2) and check virt-manager:
# strace -p 29509
Process 29509 attached - interrupt to quit
restart_syscall(<... resuming interrupted call ...> <unfinished ...>

I performed GDB analysis of this - see attachment. After system is responsive again, I can operate virt-manager but not VM's graphical console. I need to close windows with VM and open again.

Version-Release number of selected component (if applicable):
# rpm --query --all | grep -e virt-manager -e spice -e libvirt | sort
libvirt-0.9.4-23.el6_2.6.x86_64
libvirt-client-0.9.4-23.el6_2.6.x86_64
libvirt-debuginfo-0.9.4-23.el6_2.6.x86_64
libvirt-python-0.9.4-23.el6_2.6.x86_64
spice-client-0.8.2-7.el6.x86_64
spice-glib-0.6-2.el6.x86_64
spice-gtk-0.6-2.el6.x86_64

spice-server-0.8.2-5.el6.x86_64
spice-vdagent-0.8.1-3.el6.x86_64
virt-manager-0.9.0-7.el6.x86_64

How reproducible:
80%

Steps to Reproduce:
1. Create VM with spice in virt-manager
2. Try to use VM graphical console
3. Console hangs for approx 10 mins.
4. You need to wait or go to console and kill virt-manager
  
Actual results:
virt-manager frequently hangs for approx. 10 minutes, and user cannot use my system.

Expected results:
virt-manager doesn't hang

This is probably the same issue as this f16 qxl bug:

Comment 3 Stanislav Graf 2012-03-05 18:51:31 UTC 
Virt-manager settings:
menu - edit - preferences - 'Install Graphics - Spice'

Created VM contains qxl:
    <graphics type='spice' autoport='yes'/>
    <video>
      <model type='qxl' vram='65536' heads='1'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
