Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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 zhenfeng wang 2014-11-06 02:28:27 UTC 
Description of problem:
The guest agent service in rhel7 guest will be stopped after run the init shell command
Version-Release number of selected component (if applicable):
host:
libvirt-1.2.8-6.el7.x86_64
qemu-kvm-rhev-2.1.2-6.el7.x86_64
kernel-3.10.0-196.el7.x86_64
systemd-208-15.el7.x86_64

guest
qemu-guest-agent-2.1.0-4.el7.x86_64

How reproducible:
100%

Steps to Reproduce:

1.Prepare a guest including the following content
#virsh dumpxml rhel7
--
  <pm>
    <suspend-to-mem enabled='yes'/>
    <suspend-to-disk enabled='yes'/>
  </pm>
--
<channel type='spicevmc'>
      <target type='virtio' name='com.redhat.spice.0'/>
      <alias name='channel1'/>
      <address type='virtio-serial' controller='0' bus='0' port='2'/>
    </channel>

 <channel type='unix'>
      <source mode='bind' path='/var/lib/libvirt/qemu/rhel7.agent'/>
      <target type='virtio' name='org.qemu.guest_agent.0'/>
      <alias name='channel2'/>
      <address type='virtio-serial' controller='0' bus='0' port='3'/>
    </channel>


2.Start the guest, then install the qemu-guest-agent service inside the guest
#virsh start rhel7
inside guest# yum install qemu-guest-agent
inside guest# systemctl start qemu-guest-agent
inside guest# systemctl status qemu-guest-agent
qemu-guest-agent.service - QEMU Guest Agent

3.Run init 3 or init 5 command inside the guest, then, recheck the guest agent status
found the guest agent has been in inactive status
inside guest#init 3
inside guest#systemctl status qemu-guest-agent
qemu-guest-agent.service - QEMU Guest Agent

Oct 30 08:01:19 localhost.localdomain systemd[1]: Stopping QEMU Guest Agent...
Oct 30 08:01:20 localhost.localdomain systemd[1]: Stopped QEMU Guest Agent.

                                          

Actual results:
The guest agent service was stopped after run init shell command

Expected results:
The service should keep in running status
Comment 2 Miroslav Rezanina 2014-11-18 13:52:46 UTC 
Guest agent is not started on
Comment 3 Jeff Nelson 2014-12-16 21:52:52 UTC 
Deferred to rhel-7.2 as this requires a fix in redhat-release.
Comment 9 Miroslav Rezanina 2015-08-25 14:26:25 UTC 
Fix included in qemu-guest-agent-2.3.0-3.el7
