Using XtreemOS
From Xtreemos
Getting familiar with XtreemOS
If you are new to XtreemOS, you might want to take a look at the user guide. The latest version is here: XOS_UserGuide_20091014.pdf
Even if you are familiar with XtreemOS, it is recommended to look at the user guide, as it describes recent XtreemOS 2.0 features. What you should read from the guide:
- Chapter 2 (Overview)
- Section 4.3 (Application Execution Management)
- Section 4.5 (XOSAGA)
The VU Testbed
Currently the testbed consists of 3 machines:
- core.xtreemos.cs.vu.nl (core node + resource)
- node01.xtreemos.cs.vu.nl (resource + client node)
- node02.xtreemos.cs.vu.nl (resource + client node)
Note: These machine names are aliases for the following names (in order): node004.das2.cs.vu.nl, node006.das2.cs.vu.nl, node007.das2.cs.vu.nl.
Creating a user account
In order to use XtreemOS you have to be registered in a virtual organization (VO). There is a web interface through which you can request to be included in a VO – here are the steps to do this:
1. Go to the VOLifeCycle portal and make yourself a new account: [[1]]
2. Log in using this account and go to Generate new keypair. Press the Generate button and then press the Download button - this way you will get a private key (a user.key file).
3. Go to Join a VO and choose to join VU_XOS20_new (this is the virtual organization that we are currently using for tests). Write an e-mail to cstratan@cs.vu.nl and I will add you to the VO and make accounts for you on the machines.
4. After you were added to the VO, log in again to the portal and go to Get an XOS-Cert. Download the new certificate and you will have a user.crt file. With this certificate you can prove that you are in the VU-XOS20_new virtual organization.
Here the user guide for the old VU testbed (the one with XtreemOS 1.0):
