Hi, I've been quite excited running VirtualBox since I feel it's very fast. Also, reading up the user's manual, I found some nifty features such as VRDP which I still have to test out. However, I was looking for the following functionality which so far, I can't find although I saw someone referring to it in the discussion boards. Basically, what I'm looking for is the following:
"In CoW, we typically have two devices. One is the original one, say hda, and the other is the 'dirty' one,say hdb. When read is attempted for a sector, hdb is searched and returns the content of the sector if present. Otherwise, the content is read from hda. On the other hand, all writes go to hdb." (http://lists.xensource.com/archives/html/xen-devel/2004-01/msg00026.html) hdb is a separate file that can be considered a delta containing only the files added/modified. So unless you make a lot of changes, etc. hdb is usually considerably smaller than hda. This provides you with the flexibility of creating a single image with most of the packages that you need and setting that to be the 'original' and then starting several VMs concurrently with each one having it's own hdb where it writes it's changes. This is the approach used by Qemu and UML. Is the above supported by VirtualBox? If so, could you kindly illustrate how this can be achieved? Thank you for your help. -- Mathew Brown [EMAIL PROTECTED] -- http://www.fastmail.fm - A fast, anti-spam email service. _______________________________________________ vbox-users mailing list [email protected] http://vbox.innotek.de/mailman/listinfo/vbox-users
