Line 167:                         getVm().getVdsGroupCompatibilityVersion().

I would put the two validations done here in a validator (see VmValidator for 
reference) which can then be used in conjunction with valid() method to make 
code less repetitive & more readable.

The two methods would be similar to this:

class VmInterfaceValidator {

    public static ValidationResult linkingSupported(Version)

    public static ValidationResult noNetworkSupported(Version)

}

This is since I saw in next patches these two validations appear a lot 
(sometimes together, sometimes apart) and we don't want to duplicate the code 
that does it since it's harder to maintain.
