[one-users] Datastore maintenance

[Jaime Melis]

Hi,

In ONE 3.6 if you resume a VM and it doesn't work, it will go into FAIL,
and once it's in fail you cannot bring it back to RUNNING again.

I suggest you upgrade to 3.8.1 (not 3.8.0) so you don't risk losing VMs.

We're about to release 3.8.1 (couple of hours luckily) which fixes a bug
that affects VMs with CONTEXT

cheers,
Jaime
