+<section name="Setting up Tashi on a single test machine">
+
+<p>There are several dependencies you need to setup Tashi, they include:</p>
+<ul>
+<li>Apache Thrift</li>
+<li>Xen or Qemu/KVM</li>
+<li>Python 2.4 or greater</li>
+<li>MySQL or sqlite if you wish to use them as the data backend</li>
+</ul>
+<p><i>Please note that due to changes made in Thrift recently, you may need to
get an older version of the software.  The version that Tashi was developed against was from
April 11th, 2008.</i></p>
+<p>Once These are setup and configured, check out the Tashi code:</p>
+<div class="lit"><pre>
+svn co http://svn.apache.org/repos/asf/incubator/tashi/trunk ./tashi
+</pre></div>
+<p>Then, run make:</p>
+<div class="lit"><pre>
+mryan3@mryan3-d4:~/scratch/tashi$ make
+Building tashi.services...
+Generating Python code for 'services.thrift'...
+Copying generated code to 'tashi.services' package...
+Generatign Python code for 'messagingthrift'...
+Copying generated code to 'tashi.messaging.messagingthrift' package...
+Symlinking in clustermanager...
+Symlinking in nodemanager...
+Symlinking in tashi-client...
+Building nmd...
+Done
+</pre></div>
+<p>Now, you may need to need to modify some configuration parameters to make Tashi
work in your environment.  If you place a file called Tashi.cfg in etc, it will override settings
in TashiDefaults.cfg.  Some pertinent options:</p>
+<ul>
+<li>[ClusterManager]data - This specifies whether you use a pickled data file or the
SQL backend</li>
+<li>[NodeManager]VmControl - This specifies which VMM backend you use</li>
+</ul>
+<p>If you haven't installed Tashi in /usr/lib/python2.5/site-packages/ or the equivalent
folder, you must set the PYTHONPATH environment variable so that python can find the Tashi
code:</p>
+<div class="lit"><pre>
+mryan3@mryan3-d4:~/scratch/tashi$ export PYTHONPATH=`pwd`/src
+</pre></div>
+<p>Start the cluster manager (CM) first:</p>
+<div class="lit"><pre>
+mryan3@mryan3-d4:~/scratch/tashi$ DEBUG=1 ./bin/clustermanager.py 
+2009-02-19 11:19:04,276 [./bin/clustermanager.py:INFO] Using configuration file(s) ['./etc/TashiDefaults.cfg']
+2009-02-19 11:19:04,276 [./bin/clustermanager.py:INFO] Starting cluster manager
+
+
+In [1]: 
+</pre></div>
+<p>I recommend running in debug mode if you haven't got it up and running yet.</p>
+<p>Then, add your first host to Tashi.  If your box's hostname was "mryan3-d4" and
you used the pickled data format, you'd do:</p>
+<div class="lit"><pre>
+In [1]: from tashi.services.ttypes import Host
+
+In [2]: from tashi.services.ttypes import HostState
+
+In [3]: data.hosts[1] = Host(d={'id':1,'name':'mryan3-d4','state': HostState.Normal,'up':False})
+
+In [4]: data.save()
+
+In [5]:
+</pre></div>
+<p><i>If you get an error about "'unexpected keyword argument 'd'", you'll have
to downgrade to an older version of Thrift.  As noted above, the version that Tashi was built
against was from April 11th, 2008, but there are many versions that will work with Tashi.</i></p>
+<p>If you were using MySQL (or sqlite), you'd have to populate a row in the database
with columns named "id", "name", "state", and "up".</p>
+<p>Then quit the CM and restart it to force the creation of host locks.</p>
+<p>Add a user that matches both your user name and id:</p>
+<div class="lit"><pre>
+In [1]: from tashi.services.ttypes import User
+
+In [2]: data.users[13090] = User(d={'id':13090,'name':'mryan3'})
+
+In [3]: data.save()
+</pre></div>
+<p>Now, you can start the node manager (NM).  You may have to run this as root if you
have trouble gettings VMs to start as a normal user:</p>
+<div class="lit"><pre>
+root@mryan3-d4:/home/mryan3/scratch/tashi$ DEBUG=1 ./bin/nodemanager.py 
+2009-02-19 11:25:50,470 [__main__:INFO] Using configuration file(s) ['./etc/TashiDefaults.cfg']

found in /var/tmp/VmControlQemu/
+
+
+In [1]: 
+</pre></div>
+<p>After a few seconds, you should see no error messages on the NM and you should be
able to run "tashi-client getHosts":</p>
+<div class="lit"><pre>
+mryan3@mryan3-d4:~/scratch/tashi$ ./bin/tashi-client.py getHosts

+</pre></div>
+<p>Now that those are running, you can start the scheduler:</p>
+<div class="lit"><pre>
+mryan3@mryan3-d4:~/scratch/tashi$ python ./src/tashi/agents/examplepolicy.py 
+
+</pre></div>
+<p>Make sure an image is placed in /var/tmp/images (or wherever you configured it to
be):</p>
+<div class="lit"><pre>

+</pre></div>
+<p>And finally, you can use the client to try to create a VM:</p>
+<div class="lit"><pre>
+mryan3@mryan3-d4:~/scratch/tashi$ ./bin/tashi-client.py createVm --name foobar --disks CentOS-5.2-i386.qcow2
+{

+    hostId: None

+    type: 1
+    id: 1
+    hints: {}
+}
+</pre></div>
+<p>The VM will use a TAP device on your system and will be accessible over it.  If
you statically configure the guest for this test, that will work.  It is also possible to
setup a bridge and run a DHCP server on the host to provide IP addresses to the guest.  In
either case, you should be able to log into your guest shortly after that command completes.</p>

+<b>Q: Why does Tashi complain about "unexpected keyword argument 'd'"?</b>
+<br/>
+A: Tashi was originally developed against an older version of Thrift.  This is mentioned
on the <a href="documentation.html">documentation</a> page.  You will have to
downgrade to an older version of Thrift.
+</p>
+
+<p>
+<b>Q: Why does Tashi have the error message "Failed to exec gmetric, disabling"</b>
+<br/>
+A: This happens because Tashi was unable to find gmetric on your system.  gmetric is a part
of Ganglia.  It is not necessary to use Ganglia in order to use Tashi, but Tashi has the ability
to output per-VM statistics and log messages a Ganglia metrics.  If you don't care about either
of those features, you can safely ignore this message -- or turn of the use of the GangliaPublisher
class in the config file.
