Hi, I had a quick question. I''ve few machines available in a cluster. Now, if I want to install Xen on them, do I individually install in all of them (one by one); or can I have on single image available over a network/SAN and can I boot Xen from there? Are there any other smarter ways to do that? Thanks, Amitayu _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

In this area I use ( and develop) FAI (needs a Debian Server ATM), and there are some users installing their Xen VM''s with FAI. I never did that myself, but I want to work on that in the workshop I announced here yesterday.

It sounds like your talking about a COW implementation. You''ll find a lot about this in the recent archives. It doesn''t sound like it''s real reliable at the moment so a better approach may be to search the archives for "xen" and "iscsi". There''s a lot about GFS, GBND, DRBD, and other SAN technologies. I think you''ll still end up installing each system to it''s own partition, but you should be able to easily script your own solution or use something like Henning has suggested.
