Description of problem:
virt-viewer window crashes after restart libvirtd in remote host

Version-Release number of selected component (if applicable):
Host A: 10.66.5.58
# rpm -qa | grep spice
spice-glib-0.26-4.el7.x86_64
spice-gtk3-0.26-4.el7.x86_64
spice-server-0.12.4-12.el7.x86_64
spice-vdagent-0.14.0-10.el7.x86_64
# rpm -q virt-viewer
virt-viewer-2.0-4.el7.x86_64

Host B: 10.66.5.44
# rpm -q libvirt
libvirt-0.10.2-54.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Config ssh( so that host A can login host B without password.)
# ssh-keygen
# ssh-copy-id .ssh/id_rsa.pub root.5.44

2. Make sure guest rhel6u7_spice is shutdown state and Run "virt-viewer -c qemu+ssh://10.66.5.44/system rhel6u7_spice --wait" on host A, and then a "Waiting for guest domain to start" window pops up.
3. Restart libvirtd on Host B. (Must only run "service libvirtd restart one time, i cannot reproduce it after restart libvirtd more than one times continuously.)
# service libvirtd restart
4. Click gnome-terminal window and wait several seconds (the virt-viewer window won't crash if do nothing after step3).

Actual results:
virt-viewer windows crashes

Expected results:
virt-viewer should not crash.

Comment 6 Fabiano FidĂȘncio 2015-07-17 09:22:01 UTC
Moving it back to virt-viewer.

After adopting a similar approach (for handling libvirt events/mainloop integration) than the one used by libvirt-glib, xiaodwan tested http://brewweb.devel.redhat.com/brew/taskinfo?taskID=9534079 and said he was not able to reproduce the crash anymore.

Comment 7 Fabiano FidĂȘncio 2015-07-17 14:19:58 UTC
Sent the patches to the ML:

Comment 9 Xiaodai Wang 2015-07-23 05:52:48 UTC
Verified it with latest build:
virt-viewer-2.0-5.el7.x86_64

Steps to Reproduce:
1. Config ssh( so that host A can login host B without password.)
# ssh-keygen
# ssh-copy-id .ssh/id_rsa.pub root.5.44
2. Make sure guest rhel6u7_spice is shutdown state and Run "virt-viewer -c qemu+ssh://10.66.5.44/system rhel6u7_spice --wait" on host A, and then a "Waiting for guest domain to start" window pops up.
3. Restart libvirtd on Host B. (Must only run "service libvirtd restart one time, i cannot reproduce it after restart libvirtd more than one times continuously.)
# service libvirtd restart
4. Close the virt-viewer windown.

Actual Result:
No segment fault occurs.


So move it to verified.
