My environment: I am doing these things at home with the purpose of learning about virtualization techniques. My machine have quad core processor that supports Intel-VT and 8GB RAM. XEN is the virtualization platform. In short, all domUs are LVM based.

Mainly I have two questions;

  1. I need to have shared storage for these VMs. Something like NFS / NAS / iSCSI etc. However, I don't know which one is the best solution. Therefore, can someone tell me which suits best? Please note that, this shared storage need to be accessed by the other physical machines in the network.
  2. How to implement the selected solution for question #1? Any tutorials / guidelines / ebooks will be a great help and highly appreciated.

Thank you in advance :)

For #1 Best is very subjective in the space. Best in terms of cost, performance, easy to use, setup, etc. can vary a lot.

For #2, some good references here: The Running Xen book is a great resource in general (I am a co-author).

Also, I think that this is a better question for Server Fault ( and/or the Xen users list( I bet it has been discussed thoroughly on the xen-users list actually. Search here:
