Description
Suspend and Hibernate a VM. Verify it resumes as expected. For more details, see:
http://fedoraproject.org/wiki/Features/Virt_Guest_Suspend_Hibernate
Setup
Nothing beyond the initial test day setup (basically a function F18 VM).
How to test
Initiating suspend/hibernate from inside the guest
Known bugs:
- Closing a graphical window triggers a guest resume bug 871240
- Start a VM, connect to the graphical console with virt-manager
- From inside the guest, as root, run:
# pm-suspend
- Verify the state changes to 'suspended' in the main virt-manager window
- Click inside the black VM guest console, and press any key on the keyboard
- Verify the VM resumes right where it left off.
- From inside the guest, as root, run:
# pm-hibernate
- Verify the guest appears to shutdown in the main virt-manager window
- Start the guest again
- Verify that the VM resumes right where it left off
Initiating suspend/hibernate from the host
- Start the VM, connect to the graphical console with virt-manager.
- Verify the agent is running with (you should see some output):
ps axwww | grep "qemu-ga"
- From the host machine, as root, suspend the guest with virsh:
# virsh dompmsuspend f18 --target mem
- Watch virsh until the VM is listed as 'suspended':
# virsh list --all
- Wake the guest up with virsh:
# virsh dompmwakeup f18
- Using the graphical console, verify the guest appeared to resume correctly
- From the host machine, as root, hibernate the guest with virsh:
# virsh dompmsuspend f18 --target disk
- Watch virsh until the VM is listed as shutoff:
# virsh list --all
- Start the quest again
- Verify that the VM resumes right where it left off
Expected Results
No obvious errors encountered, guests seem to be functioning as normal after resuming.
