[one-users] VM hangs in pending state with KVM

[Javier Fontan]

Hello,

The problem is that the monitorization script is not getting
TOTALMEMORY. Go to the execution host as oneadmin user, enter dir
/tmp/one-im and execute the biggest stript as this:

$ ruby -wd <name of the script> and send me the output. There should
be some problem getting information.

Bye

> Nothing is copied from the front-end to the worker-node; no image and no
