Just out of curiorsity does Windows run inside VirtualBox or does VirtualBox run inside Windows? Or, put another way, does one install VirtualBox on a blank hard disk and then install Windows and Linux etc?Also, out of curiosity, doesn't the use of VirtualBox (or equivalent) use up a significant amount of the PC's performance before any OS gets a look in?I have been thinking about something like this but I have never tried it....R
take a snapshot of your guest while it is pristine
you can run it [ubuntu] from a USB flash drive. Here are the Instructions on the Ubuntu site
I'd gladly sacrifice boot time and ram for the "live" image to have a USB stick I could insert "anywhere" and run MY unix environment...
So can I use the live boot USB drive with a small file system ALSO on the USB drive? (saved config, user file, user documents, etc, all in real files on the flash drive.)
The only thing that can be installed on a blank hard drive so that you can boot it is an operating system (because the definition of an operating system is that you can boot it), so your question about installing it on a blank hard drive is equivalent to asking "Is VirtualBox literally an installable operating system like Linux"? Which is an interesting question and the answer is "No". As far as I know neither virtualbox, nor VMWare, nor QEMU nor any number of other other options can literally be an operating system themselves that you can install on a blank hard drive.
