Red Hat Bugzilla – Bug 800017
spice guest can hang host x server
Last modified: 2014-06-18 05:15:24 EDT
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
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
virt-manager frequently hangs for approx. 10 minutes, and user cannot use my system.
virt-manager doesn't hang

This is probably the same issue as this f16 qxl bug:
menu - edit - preferences - 'Install Graphics - Spice'
Created VM contains qxl:
<graphics type='spice' autoport='yes'/>
<model type='qxl' vram='65536' heads='1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
