2015-09-07 11:33:34 -0500 asked a question why application don't restart after start a previously checkpointed virtual machine

Hello, i run a intel benchmark (multi pingpong) on one virtual machine, i suspend the virtual machine and i take a checkpoint of the virtual machine. After saving (or checkpointed) the virtual machine, i start the checkpointed virtual machine (the image of the checkpointed VM) on a différent host. i realize that the virtual machine don't start completly, the boot process is stoped. And then, my benchmark is not restarted. I want to know what can be the problem. Thks. Hope to read you. Best regard.

2015-07-03 04:30:23 -0500 asked a question How to restart a job in a VM that was previously snapchoted ?

I have an image of a Ubuntu system. I create 4 VMs and run a benchmark. I then snapshot all 4 VMs. When i restart these VMs with "nova boot --image" command line, the benchmarl don't restart and don't appear. Is the benchamrk have to be in the first image ?

So my question is how to restart a job in a VM that was previously snapchoted ?

Thks. Hope to read you. Best regards.

Hello, While checkpointing a VM with openstack, i get this error message in nova-compute log : " error launching a defined domain with XML " and this : " ERROR oslo.messaging.rpc.dispatcher [req-8dcd07ef-f019-488f-8904-f44b83659f31 ] Exception during message handling: invalid argument: Backing file '/var/lib/nova/instances/_base/a78d6646a34610a839a9ad2f0cfa4f1df96f1267' of image '/var/lib/nova/instances/89d7324e-49ed-4b87-94d3-5878c908141b/disk' is missing "

So the snapshot didn't work. What can be the problem.
