Installing OS X Mountain Lion from DVD

This is sort of a repost, since I have done a bare-metal install of OS X previously.  I thought I would update my thread based on the new release - as Apple has introduced... more changes?  Ugg... NOTE: I would NOT recommend going to Mountain Lion Server.  It is actually fairly cheesy and a disappointment.  I say it is cheesy as it now seems like having a "Server" is just an application - that is due to the fact that you now install the "Workstation" release and then purchase/install Server.app.  Fair enough - I guess a Server is simply a few more daemons and configuration files and startup scripts.  Either way this presentation of what a *nix server is, deflated my ego a bit.  But, here is the primary reason I do not recommend moving "forward" to the new release.  The management interface.  I think it is horrible.  I suppose I don't like change (for the sake of change) and this new release certainly seems as though that is exactly what Mountain Lio

Migrating Volume between Volume Groups (RHEL)

Issue:  I have 2 x 2 Disk Software RAID arrays in my host running a number of Virtual Machines.  Initially I had created all of the VMs on the same disks as the OS (2 x 500GB RAID 1) and I would like to spread them out.
