Installation USB flash drive for XenServer and/or Xen Cloud Platform(XCP)

In a previous post presented the oMiCloud and promised to write some guides to help towards setup of such a lab.

Atlas  (i.e the machine with  XenServer in my home lab) is an Intel NUC DC3217IYE and has no CD or DVD drives but  only USB ones. Therefore for the installation of XenServer, a USB flash drive has been used. I have used a Corsair Voyager 16GB disk but any USB flash drive with space more than a gigabyte would be fine.

Bellow are the steps of one can create and installation USB.
  1. Format your thumb drive using FAT32
  2. Use UNetbootin to burn the XenServer or XCP iso to your USB drive.
  3. Open your thumbdrive
  4. Rename the file syslinux.cfg to syslinux.cfg.bak
  5. Rename the folder boot/isolinux to boot/syslinux
  6. Rename the file boot/syslinux/isolinux.cfg to boot/syslinux/syslinux.cfg
  7. Rename the file boot/syslinux/isolinux.bin to boot/syslinux/syslinux.bin
This has successfully worked with:

 XenServer, versions 6.0, 6.1 & 6.2.
 Xen Cloud Platform (XCP), versions  1.5  (beta) & 1.6.

NOTE for MacOSX users ...
  In the case of MacOSX  use "Disk Utility" to format your drive and create the required partition layout i.e set  "Partition Layout " to "1 Partition" and in the options do not forget to enable "Master Boot Record"

P.S 2  stay tuned in a next post I will go through the steps to install CloudStack management server.

Enjoy !!!

The oMiCloud is here!

oMiCloud is the name of my home-lab!!!

And this post is all about it. Actually is a brief description and the specs of the  machines currently used.  

Well ... the  lab in present is based on just three machines.

 The first machine is the so called Cerberus. This machine purpose is twofold. The most important  role is to act as firewall, responsible to provide access to the 3rd party external users (i.e allow access to friends only). The second role is to host a small web server, used for management panels and a couple of funny private WIKI.

 Kerberos is a low power (in terms of electric consumption) but powerful SheevaPlug, and here is  the specs. 

 The second machine is Atlas.  This machine is the most powerful machine of the network so far. The whole cloud infrastructure is mainly based on Atlas. It is runs the open source Xen Cloud Platform  (XCP version 1.6) and is the main resource for CloudStack . Its actually the host of all the VMs run on the lab (at least for now).Atlas in an Intel Next Unit of Computing (NUC). To be more specific a  DC3217IYE with 16GB of RAM (i.e 2 X Corsair Vengeance 8BG SO-DIMMs) and 256GB SSD disk (i.e Plextor m5m SSD ).

 The third and the last (for now) machine of my home lab is MenippusMenippus is also a SheevaPlug, like Cerberus and its main purpose is monitoring (Zennos used so far). Stay there, watch the lab, and apply some cynic philosophy (mainly through alerts).

 Promise some guides and how-to will be follow in the next days in order to help all my Geeky friends build their own home-labs.

P.S well … there is also a Network attached storage (NAS) but nothing that  really worth mentioning further ...
