<div>Hi Ruben,</div>
<div><br>
</div>
<div>Thanks for the message. (It's still confusing to me though.)</div>
<div><br>
</div>
<div>Let me see if I understand this right.</div>
<div><br>
</div>
<div>In "Merge Use Case" section of <a href="http://docs.opennebula.org/4.4/user/virtual_resource_management/vm_guide.html">http://docs.opennebula.org/4.4/user/virtual_resource_management/vm_guide.html</a> </div>
<div>suppose there is VM_RESTRICTED_ATTR="CPU" in oned.conf.</div>
<div>This only prevents non-oneadmin-group users from </div>
<div>using —cpu option to onetemplate instantiate command</div>
<div>but it (VM_RESTRICTED_ATTR="CPU" in oned.conf) does NOT prevent users from using</div>
<div>CPU attribute in their VM templates. Is this right?</div>
<div><br>
</div>
<div>In ON3.2, src/vm/VirtualMachineTemplate.cc has the following code</div>
<div>[A] =</div>
<div>const string VirtualMachineTemplate::RESTRICTED_ATTRIBUTES[] = {</div>
<div> "CONTEXT/FILES",</div>
<div><span class="Apple-tab-span" style="white-space:pre"></span>"DISK/SOURCE",</div>
<div> "NIC/MAC",</div>
<div> "NIC/VLAN_ID",</div>
<div> "RANK"</div>
<div>};</div>
<div><br>
</div>
<div>We know that this prevents non-oneadmin-users from using for example CONTEXT/FILES attribute in their template</div>
<div>so we had to modify the above to comment out CONTEXT/FILES and RANK.</div>
<div><br>
</div>
<div>But it looks like this array is gone now but the new entries in oned.cof (VM_RESTRICTED_ATTR) has NOT inherited the functionality.</div>
<div><br>
</div>
<div>So, in summary, looks like there is restriction that prevents normal users from using</div>
<div>those attributes [A] in their templates.</div>
<div><br>
</div>
<div>Do I understand right?</div>
<div><br>
</div>
<div>Thanks again,</div>

<div dir="ltr">Hi Hyun
<div><br>
</div>
<div>We've taken a look into it and it seems to be working. A couple of notes:</div>
<div><br>
</div>
<div>1.- VM Template is checked for restricted attributes if the owner is not oneadmin (or in oneadmin group). The rationale behind it is that oneadmin can prepare templates with "unsafe" attributes but let the user instantiate them (but not set or modify the
attributes). We'll make it clearer in the doc.</div>
<div><br>
</div>
<div>2. Disk snapshot operation may use the SOURCE attribute but internally, the user cannot modify or set the SOURCE attribute.</div>
<div><br>
</div>
<div>Hope it makes it clearer.</div>
<div><br>
</div>
<div>Cheers</div>
<div><br>
</div>
<div>Ruben</div>

<div>There is not much to it, it should be working as you describe. We'll try to reproduce it and fix it for 4.6 if it's broken.</div>
