Since creating an OpenPGP key requires some randomness (eg. move mouse, reading or writing from/to File System), the process of creating it on a remote connected host (via ssh) may take a lot of time or even get stuck.

I have several virtual linux guests running on VirtualBox: a bunch of test machines to which I connect exclusively via ssh from my host terminal.

No dvd at home, only a 4GB usb stick but in need to install Fedora on a laptop..
