I have been trying to create a four-node slice for testing GEMINI. This slice contains three VMs in a mesh network configuration and one stand-alone VM. When I try to create this sliver, I am getting at least one node failure most of the time. This morning I have tried at least 12 slivers so far and all but two have had at least one node fail. The sliverstatus output does not give any geni_error indication as to what caused the failure.

{'geni_error': ,

'geni_status': 'failed', 'geni_urn': 'urn:publicid:IDN+utah.geniracks.net+sliver+10467', 'pg_manifest': {'attributes': {'client_id': 'PCC',

'component_id': 'urn:publicid:IDN+utah.geniracks.net+node+pc1', 'component_manager_id': 'urn:publicid:IDN+utah.geniracks.net+authority+cm', 'exclusive': 'false', 'sliver_id': 'urn:publicid:IDN+utah.geniracks.net+sliver+10467', 'xmlns': 'http://www.geni.net/resources/rspec/3', 'xmlns:gemini': '​http://geni.net/resources/rspec/ext/gemini/1'},

I have left slice johGEM1209261119 up in case someone wants to take a look at one of the failures.

I have created several slivers in the last couple of weeks where one or more of the four nodes (VMs) have not had their SSH keys configured correctly. IOW, I get a password prompt when attempting to log in to the node. I ran into the same problem today and left the slice up in case someone wants to troubleshoot. The slice is johGEM1209261101. I can only log into node PCA (pc1.utah.geniracks.net -p 31035). The rest present the password prompt.

Luisa has reproduced the same problem in two of her slices today.

This ticket will capture the process followed to build a VM custom image for OpenVZ containers. Using the existing instructions, the following steps will be completed:

1. Create an Experiment with an existing image
2. Login to node and customize
3. Create a new Image Descriptor and snapshot
4. Wait for the email saying the image creation is done
5. Verify new customized image
6. Make image available

Background: The following email exchange kicked off this effort:

2) We have support for making disk images of VMs (OpenVZ containers) - from a user perspective, it looks basically the same as making an image from a bare metal node. We have our first guinea pig^HH^HH^HH^HH^HH user trying it out right now.

If you need a 2nd guinea pig... just point me to the instructions.

There are no instructions it looks the same as doing it for a bare metal node.

So the existing instructions now needd to be modified to remove all instances on "physical nodes"? Sounds good, I will use the existing instructions.
