[vbox-dev] Fw: Setting HPET via SOAP

Hi Klaus. Thank you for your quick answer! Sure, vm machine is turned off. I trying to turn HPET on after snapshot is restored (machine is down) but got this error. And yes , as I understand from SDK, such settings shall work with mutable machine. Setting RAM size works fine, but HPET failed. I specify that  IMachine_setCPUHotPlugEnabled doesn't work this way. Few month ago we were try to set videocapturing on and also no positive results. Could it be a defect with processing boolean values when we work with vboxwebsrv? 
Regards, Yuriy

Hi Guys! Forum  moderator suggests me to contact somebody from developers to solve my problem faster than waiting answer on forum. 
I have a trouble setting boolean values via SOAP for VBOX. 
Actually, I need to set IMachine_setHPETEnabled to True programmatically, but IMachine_setCPUHotPlugEnabled also doesn't work. 
Trying to set these parameters always follows with Machine is not mutable error. But setting of memory like in SDK example works fine. 
What I'm actually do. I using suds SOAP client library for Python. 
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. 

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...).
