[one-users] Contextualization and Ubuntu hda/sda confusion

[Javier Fontan]

Hello,

We also had these problems with libvirt/kvm. Even if we specify the
target device as the user wants it takes that as a hint and not always
sets the bus as expected (hd*/sd*). We will try to find a way to force
it to use the target specified but right now you have to check
libvirt/kvm bias in bus selection.

Bye
