#2 fixed Unable to use OpenVZ resources in slivers somebody lnevers@bbn.com
Description

Using version ??? on 04/25/2012, sent email to instageni-ops@flux.utah.edu:

Created a sliver with 2 OpenVZ hosts, the sliver was created successfully, but the sliverstatus shows that the 'pg_status' is 'not ready'. Attempts to login to the 2 nodes fail with a timeout. Connections were attempted over 40 minutes after sliver creation. This problem is reproducible

At this point, we are still debugging some problems in our OpenVZ image - our older Fedora 10 based image has trouble booting on the machines in these racks, and so we've had to move to a newer Fedora 15 image. We've resolved several obstacles with that image, but there are still a few kinks to iron out. We will keep you updated.

#3 fixed listresources state mismatch for available nodes somebody lnevers@bbn.com
Description

Based on the listresources, the aggregate shows all nodes as available, but creating a sliver with two node of sliver_type "raw-pc" results in a failure that stated the the nodes requested are not available.

The full listresources output will be attached to the ticket, and the sliver creation error is shown here:

#4 fixed Requesting link without specifying capacity results in mapper failure, no bandwidth default available. somebody lnevers@bbn.com
Description

Using version?? on 04.30.2012:

This issue was discussed on the InstaGENI maillists, entering ticket to track resolution.

In a scenario where a sliver is created without specifying the "capacity" value, the createsliver results in a mapper error. Following are the RSpec lines that cause the failure:

  <link client_id="insta1-and-insta2">
    <interface_ref client_id="insta1:if1"/>
    <interface_ref client_id="insta2:if1"/>
    <property source_id="insta1:if1" dest_id="insta2:if1"/>
    <property source_id="insta2:if1" dest_id="insta1:if1"/>
  </link>

The modified "property" lines that resolve the problem:

  <link client_id="insta1-and-insta2">
    <interface_ref client_id="insta1:if1"/>
    <interface_ref client_id="insta2:if1"/>
    <property capacity="1000000" source_id="insta1:if1" dest_id="insta2:if1"/>
    <property capacity="1000000" source_id="insta2:if1" dest_id="insta1:if1"/>
  </link>

The mapper failure reported when using the "property" without a bandwidth specified, is shown here:
