Comment 4 Itamar Heim 2012-06-10 09:02:31 UTC

rami - care to check if still relevant?

thanks,
   Itamar

Comment 5 Greg Padgett 2012-06-13 01:01:56 UTC

Hi Rami, I attempted to reproduce the bug by issuing the following 2 REST requests to create a template and then a storage pool using that template.  On the current code, both requests succeeded and I saw no exceptions being thrown in the log.

First, the template:

POST /api/template
<template>
  <name>Test_Template</name>
  <vm id="75223ae5-fa30-4f05-add8-6af0260a76db" />
</template>

This was of a small VM, 256MB RAM and 1GB disk.  Next, I created a pool of 50 with the following:

POST /api/vmpools
<vmpool>
  <name>Test_Pool</name>
  <size>50</size>
  <description>Pool of 50 VMs for bug 770420</description>
  <cluster href="/api/clusters/3b2adada-b006-11e1-b8e6-c3c3da6ad753" id="3b2adada-b006-11e1-b8e6-c3c3da6ad753" />
  <template href="/api/templates/852fdb94-4cf1-40f1-8491-debf67fcda29" id="852fdb94-4cf1-40f1-8491-debf67fcda29" />
</vmpool>

(FYI, the cluster specified uses local storage.)

If this bug is still relevant (per Itamar's question in comment 4), are there additional details you recall that may help reproduce the problem?  Thanks.

Comment 6 Rami Vaknin 2012-06-13 07:59:15 UTC

Not reporducible on upstream with last commit's hash: 0f298ab06222be0121faa9e2b400f59ddec22d35

In addition, I have not encountered with these exceptions a lot of time.
