Backing up Virtual Machines
Today's VM systems can use "snapshots" to effectively capture an image of the VM at a moment in time. Microsoft calls this "Shadow Copy" but it's all the same idea: copy on write. The snapshot software creates a file that looks like a copy of the VM image, but it isn't. At that moment, it's actually working like a hard link: it is pointing to exactly the same disk blocks as the original file. If some process writes data to any block in the original, the target block is first copied to a new block that the snapshot file will use.
VMware Networks, Bridged vs. Nat vs. Host What to do with the $6,000.00 server? I suggested putting Linux and VMware on it - heck, it's a big, powerful box, it seems a shame to have it go to waste (and we both thought that running Windows 2003 Server was definitely a "waste").
Wake up, Apple Apple needs to pull its head out of the sand on this. Virtualization is the most important technology right now. Microsoft blew it (but they never really had a chance anyway because virtualization hurts them as much or more than it helps them) and VMware has made the first strike, but it's not too late for Apple to ink their own deal.
