    5353 * The site administrator can determine how many nodes are allocated for OpenVZ or !PlanetLab use, and how many are available for experimental use, right now.

     57 * As a site admin:
     58   * Browse to [https://boss.utah.geniracks.net/nodecontrol_list.php3?showtype=dl360]
     59   * Login
     60   * Enter red dot mode
     61   * The white dots in the "Up?" column and lack of Name/PID/EID info show that pc1, pc2, and pc4 are available for experimenter use, and are not in use right now
     62   * pc3 and pc5 are in use.  Of these:
     63     * pc5 is in an special experiment, `emulab-ops/shared-nodes`, and is running the OS `FEDORA15-OPENVZ-STD`.  It's a reasonable guess that this is the OpenVZ shared node, which provides Fedora 15 VMs to experimenters.  Browsing to [https://boss.utah.geniracks.net/showexp.php3?pid=emulab-ops&eid=shared-nodes#nsfile], corroborate that by finding the setting:
     64{{{
     65tb-set-node-sharingmode $vhost1 "shared_local"
     66}}}
     67     * pc3 is not special.  It is an experimental node which is in use.
     68   * Thus, a site admin can learn that the current allocation is 1 OpenVZ node, 0 !PlanetLab nodes, and 4 experimental nodes.
     69 * As an experimenter, run:
     70{{{
     71omni -a http://www.utah.geniracks.net/protogeni/xmlrpc/am listresources -o
     72}}}
     73 and view the output.  Learn the following things:
     74   * the node entry for pc3 has a field showing it's unavailable (this is "true" for e.g. pc1):
     75{{{
     76       <available now="false"/>   
     77}}}
     78   * the node entry for pc5 contains these lines (10034 is the OSID for FEDORA15-OPENVZ-STD, though i don't know how you'd know that as an experimenter.  But "pcshared" seems like a clue):
     79{{{
     80       <emulab:fd name="pcshared" violatable="true" weight="1.0"/>   
     81       <emulab:fd name="OS-10034" weight="0.5"/>   
     82}}}
     83   * also, the node entry for pc5 contains 49 slots of type "pcvm", whereas the other nodes contain 50.  I bet that is a clue to how many VMs pc5 thinks it can run, since i have one VM allocated on there right now (that is, i bet pc5 thinks it can allocate 50 VMs):
     84{{{
     85      <hardware_type name="pcvm">
     86          <emulab:node_type type_slots="49"/>
     87      </hardware_type>
     88}}}
