            <p class="xfmc4">Hi Guys!</p>
            <p class="xfmc4">Forum  moderator suggests me to contact
              somebody
              from developers to solve my problem faster than waiting
              answer on forum.</p>
            <p class="xfmc4"><br/>
              I have a trouble setting boolean values via SOAP for VBOX.<br/>
              Actually, I need to set IMachine_setHPETEnabled to True
              programmatically, but
              IMachine_setCPUHotPlugEnabled also doesn't work.<br/>
              Trying to set these parameters always follows with Machine
              is not mutable
              error. But setting of memory like in SDK example works
              fine.<br/>
              What I'm actually do. I using suds SOAP client library for
              Python.<br/></p>
          </span></blockquote>
      </span></blockquote>
    This doesn't sound like a problem with specific bindings to me
    (never used suds though, only used ZSI as you can see in the samples
    in the SDK). From the symptoms you're using the wrong IMachine
    reference. On the other hand, I can't explain why setting the memory
    size with the same reference works, it's doing the exact same checks
    on the API implementation side.<br/><br/>
    Are you sure that the snapshot you are restoring is an "offline"
    one, i.e. for a powered off VM? Otherwise the VM is in saved state,
    which means no significant reconfiguration is possible (but again,
    same rules for HPET and memory size...).<br/><br/>
