RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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 Fidêncio 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 Fidêncio 2015-07-17 14:19:58 UTC 
Sent the patches to the ML:
https://www.redhat.com/archives/virt-tools-list/2015-July/msg00063.html
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.
