You could store the virtual hard disks in an encrypted volume, even a TrueCrypt file. Normally I would recommend against TrueCrypt files, since metadata like filenames can leak onto the unencrypted parts of the hard drive, but the names of files in a virtual hard disk shouldn't leak, since only the OS running in VirtualBox sees them. Likewise, the content of log files shouldn't leak. Alternatively, you don't have to use the Workstation that Whonix provides. You can install your own operating system with FDE. I wrote a guide on how to do that. It's really easy, the whole thing boils down to manually configuring the IP address, gateway and DNS. The hardest part is figuring out how to do that on some operating systems. http://dkn255hz262ypmii.onion/index.php?topic=161335.msg1148298#msg1148298 It's more secure than the other options, but probably too advanced for most people in this community. I would love to see a Qubes Live image. Get the features of Qubes in a burn-and-boot solution. The default configuration would launch the TorVM and run the other VMs through it, create disposable VMs in RAM for opening certain filetypes, and maybe offer a persistent volume.
