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:
Guest agent won't work if excute the "guest-sync-delimited"'s qemu-guest-agent command twice
Version-Release number of selected component (if applicable):
qemu-kvm-rhev-1.5.3-19.el7.x86_64
libvirt-1.1.1-13.el7.x86_64
kernel-3.10.0-47.el7.x86_64
qemu-guest-agent-1.5.3-19.el7.x86_64.rpm
virtio-win-1.6.7-2.el7.noarch
How reproducible:
100%
Steps to Reproduce:
1.Prepare a running guest with the following xml
# vrish dumpxml rhel7
--
<pm>
<suspend-to-mem enabled='yes'/>
<suspend-to-disk enabled='yes'/>
</pm>
--
<channel type='unix'>
<source mode='bind' path='/var/lib/libvirt/qemu/rhel7.agent'/>
<target type='virtio' name='org.qemu.guest_agent.0'/>
<alias name='channel1'/>
<address type='virtio-serial' controller='0' bus='0' port='1'/>
</channel>
2.Install the qemu-guest-agent packet in the guest, then start the qemu-guest-agent service
#systemctl start qemu-guest-agent
3.Excute the following qemu-guest-agent command twice, the guest agent won't work
# virsh qemu-agent-command --domain rhel7 '{ "execute": "guest-sync-delimited", "arguments": { "id": 123456 } }'
error: internal error: cannot parse json �{"return": 123456}: lexical error: invalid char in json text.
�{"return": 123456}
(right here) ------^
# virsh qemu-agent-command --domain rhel7 '{ "execute": "guest-sync-delimited", "arguments": { "id": 123456 } }'
error: Guest agent is not responding: QEMU guest agent is not available due to an error
4.Shutdown the guest with the guest-agent, it report error // normally, the guest can be shutdown successfully with the guest-agent
# virsh shutdown rhel7 --mode agent
error: Failed to shutdown domain rhel7
error: Guest agent is not responding: QEMU guest agent is not available due to an error
5.Both the windows and rhel's guest can hit the issue
6.It works well with qemu-kvm command
# nc -U /tmp/qga.sock
{"execute":"guest-ping"}
{"return": {}}
{ "execute": "guest-sync-delimited", "arguments": { "id": 123456 } }
�{"return": 123456}
{ "execute": "guest-sync-delimited", "arguments": { "id": 123456 } }
�{"return": 123456}
{ "execute": "guest-sync-delimited", "arguments": { "id": 123456 } }
�{"return": 123456}
Actual results:
Guest agent won't work if excute the "guest-sync-delimited"'s qemu-guest-agent command twice
Expected results:
The guest agent should work well
