Please tell me, the error
'No space left on device' —
which disk is it referring to, and what could be causing this error?  

[Jorge Moreira]

The error occurs when calling clone with the CLONE_NEWPID flag, according to the manual:

ENOSPC (since Linux 3.7)
              CLONE_NEWPID was specified in the flags mask, but the limit
              on the nesting depth of PID namespaces would have been
              exceeded; see pid_namespaces(7).

You can run with sandboxing disabled or figure out how to increase the nesting depth limit in your ubuntu VM.
