[one-users] problem running vm context image

[Javier Fontan]

Can you connect using VNC to the VM and check that the context cdrom
can be seen at /dev/sdb? It may be misplaced. Search in /dev for files
owned by cdrom user/group.

We are preparing more robust contextualizacion scripts/packages for
the next version [1] that will search for the context cdrom in more
places. Sometimes hypervisor/linux distro changes the device where the
context CD is seen.
