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 yafu 2017-11-09 10:10:06 UTC 
Description of problem:
Listen type changed to 'none' after managedsave/restore guest with spice listening on an auto-generated unix socket

Version-Release number of selected component (if applicable):
libvirt-3.9.0-1.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Enable spice_auto_unix_socket in /etc/libvirt/qemu.conf and restart libvirtd:
spice_auto_unix_socket = 1

2.Prepare a guest with xml:
#virsh edit rhel7.3-min
...
    <graphics type='spice' port='-1' autoport='yes'>
      <listen type='address'/>
    </graphics>
...

3.Start the guest:
#virsh start rhel7.3-min

4.Check the spice device:
#virsh dumpxml rhel7.3-min
...
<graphics type='spice'>
      <listen type='socket' socket='/var/lib/libvirt/qemu/domain-10-rhel7.3-min/spice.sock'/>
    </graphics>
...

5.Do managedsave and restore:
# virsh managedsave rhel7.3-min
Domain rhel7.3-min state saved by libvirt
# virsh start rhel7.3-min
Domain rhel7.3-min started

6.Check the spice device again:
#virsh dumpxml rhel7.3-min
...
   <graphics type='spice'>
      <listen type='none'/>
    </graphics>
...

Actual results:
Listen type changed to 'none' after managedsave/restore guest with spice listening on an auto-generated unix socket

Expected results:
listen type should not change after managedsave/restore guest with spice listening on an auto-generated unix socket

    conf: fix migratable XML for graphics if socket is generated based on config
Comment 6 Fangge Jin 2017-12-28 02:46:55 UTC 
Reproduced on build libvirt-3.9.0-4.virtcov.el7.x86_64

Verified on build libvirt-3.9.0-6.el7.x86_64

After managedsave, dumpxml:
# virsh managedsave-dumpxml rhel7-min
...
    <graphics type='spice' autoport='yes'>
      <listen type='address'/>
    </graphics>
...

Restore guest:
# virsh start rhel7-min
Domain rhel7-min started

# virsh dumpxml rhel7-min
...
    <graphics type='spice'>
      <listen type='socket' socket='/var/lib/libvirt/qemu/domain-2-rhel7-min/spice.sock'/>
    </graphics>
