Hi,

Checked the logs and see the following:

02:42:05 [WARNING] OVF does not contain a valid image description, using default.
02:42:05           The following CPU types are supported by this host:
02:42:05                 - model_Westmere: Intel Westmere Family
02:42:05                 - model_Nehalem: Intel Nehalem Family
02:42:05                 - model_Penryn: Intel Penryn Family
02:42:05                 - model_Conroe: Intel Conroe Family
02:42:05 [ ERROR ] Failed to execute stage 'Environment customization': Invalid CPU type specified: model_SandyBridge

Barak thinks that it may be related to the recent update in the Lago code.

Gal, any idea ?

Thanks in advance,
Lev Veyde.
