14.9.2. Shutting Down Red Hat Enterprise Linux 6 Guests on a Red Hat Enterprise Linux 7 Host

Procedure 14.4. Workaround for Red Hat Enterprise Linux 6 guests

1. Install the acpid package

   The acpid service listen and processes ACPI requests.
   Log into the guest virtual machine and install the acpid package on the guest virtual machine:

   # yum install acpid

   Copy to clipboard

2. Enable the acpid service

   Set the acpid service to start during the guest virtual machine boot sequence and start the service:

   # chkconfig acpid on
   # service acpid start

   Copy to clipboard

3. Prepare guest domain xml

   Edit the domain XML file to include the following element. Replace the virtio serial port with org.qemu.guest_agent.0 and use your guest's name instead of $guestname

   
   <channel type='unix'>
      <source mode='bind' path='/var/lib/libvirt/qemu/{$guestname}.agent'/>
      <target type='virtio' name='org.qemu.guest_agent.0'/>
   </channel>

4. Install the QEMU guest agent

   Install the QEMU guest agent (QEMU-GA) and start the service as directed in Chapter 10, QEMU-img and QEMU Guest Agent. If you are running a Windows guest there are instructions in this chapter for that as well.

5. Shutdown the guest

   1. Run the following commands

      # virsh list --all  - this command lists all of the known domains
         Id Name              State
      ----------------------------------
         rhel6                running
      

      Copy to clipboard
   2. Shut down the guest virtual machine

      # virsh shutdown rhel6
      
      Domain rhel6 is being shutdown
      

      Copy to clipboard
   3. Wait a few seconds for the guest virtual machine to shut down.

      # virsh list --all
       Id Name                 State
      ----------------------------------
        . rhel6                shut off

   4. Start the domain named rhel6, with the XML file you edited.

      # virsh start rhel6

      Copy to clipboard
   5. Shut down the acpi in the rhel6 guest virtual machine.

      # virsh shutdown --mode acpi rhel6 

      Copy to clipboard
   6. List all the domains again, rhel6 should still be on the list, and it should indicate it is shut off.

      # virsh list --all
         Id Name                 State

      # virsh shutdown --mode agent rhel6

      Copy to clipboard
   9. List the domains. rhel6 should still be on the list, and it should indicate it is shut off

      # virsh list --all
         Id Name                 State
