[one-users] 3.4.0 and HISTORY

[Carlos Martín Sánchez]

Hi Chris,

It is indeed a bug. At first I wasn't able to reproduce the problem, then I
realized you were creating VM directly from a template file rather than
using onetemplate.

We are looking into it [1]. Meanwhile, could you please try to create the
VMs with "onetemplate instantiate" [2], and see it the problem disappears?

Regards,
Carlos
