Public bug reported:
[ Impact ]
On ARM64, VM's can not wakeup after a dompmsuspend is issued.
[Test Case]
Configure a system with Xenial, install qemu from cloud-archive:pike
Install: qemu-efi virt-manager libvirt-bin qemu-guest-agent qemu-system-aarch64
qemu-system-aarch64:
Installed: 1:2.10+dfsg-0ubuntu3.1~cloud0
Candidate: 1:2.10+dfsg-0ubuntu3.1~cloud0
libvirt-bin:
Installed: 3.6.0-1ubuntu5~cloud0
Candidate: 3.6.0-1ubuntu5~cloud0
On the test system:
1. create a virtual machine that runs fine (in this example Ubuntu 17.10)
2. Install qemu-guest-agent on the VM
qemu-guest-agent:
Installed: 1:2.10+dfsg-0ubuntu3.1
Candidate: 1:2.10+dfsg-0ubuntu3.1
3. Power off the VM and edit the xml to enable qemu-guest-agent:
<channel type='unix'>
<target type='virtio' name='org.qemu.guest_agent.0'/>
<address type='virtio-serial' controller='0' bus='0' port='1'/>
</channel>
4. suspend it
$ sudo virsh dompmsuspend ubuntu1710 --target mem
Console will report:
$ sudo virsh dompmsuspend ubuntu1710 --target mem
Domain ubuntu1710 successfully suspended
5. confirm that the VM suspends
virsh-list will still identify the VM as running however the VM is now
inaccessible via console. We appear to be suspended. But no logs can be found
actually confirming this is happening.
3. wake it up
$ sudo virsh dompmwakeup ubuntu1710
Domain ubuntu1710 successfully woken up
Observed Result:
The VM will never wakeup, the console will not respond to keystrokes, the
VM must be reset in order to recover it.
Expected Result:
The VM wakesup as expected and is fully functional
