[Bug 1451941] Re: nova-compute-flex is broken due to missing python dependencies

[James Page]

nova-compute-flex is present in the Kilo UCA; it might be present in
later pockets if the cleanup process has not been running.

Please switch to using nova-compute-lxd as this superceeded nova-
compute-flex in later releases.

** Changed in: nova (Ubuntu)
       Status: New => Won't Fix
