[one-users] overcommit of cpu and memory under kvm

[Ruben S. Montero]

Hi,

If you are seeing FOO=bar in the template that shows that the informations
flow is right, and one.db updated. Could it be that the values  generated
by the modified kvm.rb change from execution to execution?

Cheers

Ruben
