Hi,<br>
<br>
About why the memory setting can be changed, could it the same
underlying issue than this one?<br>

Ah, python 3.x support for the ZSI bindings is on the todo list,

Yes and no. When there is a properly established session there are
two IMachine objects for every "VM", one readonly (the one you'd
get when digging out the IMachine object when there is no session)
and one mutable. You're definitely using the right one, otherwise
you wouldn't get the error message below. So that's good news,
your code for establishing the session etc. is correct.<br>

Ah, there you go. I asked you already what kind of snapshot you're
restoring - and it's clearly an online snapshot. In such a case
you can't change the settings, as the VM isn't powered off. So as
I suspected a few mails ago, your assumptions are wrong.<br>
<br>
To repeat: a VM in state "Saved" can't be significantly
reconfigured, because it is logically still running, with the
entire hardware state saved (a bit like a hibernated PC, where one
also has to keep fingers off the hardware config). It's simply not
possible to enable HPET in this situation. It would be if you
throw away the saved state, but I'm not sure if that's making the
overall situation worse.<br>
<br>
So what you're seeing is 100% expected and correct behavior. The
only mystery is why the memory size can be changed, because that
shouldn't be possible either.<br>

<div>Just for your information. It seems to me a little
strange that when vbox server returning an error it used not
the same value in returnval as my mutable machine id. It
increased each time request being sent to server. Here is
what SOAP ui shows:</div>

<div> </detail></div>
<div> </SOAP-ENV:Fault></div>
</div>
</span></blockquote>
I don't follow - the returned reference is not for IMachine, it is
an error object (IVirtualBoxError) which describes the error in
more detail than what the SOAP fault code can do. Each fault
creates a new error object, which explains why a new reference is
created.<br>
<br>
Phew, at least the biggest mystery is resolved.<br>

Can't tell from here what's "going over the wire" with
your code, but as long as the error message has the
word "mutable" in it I wouldn't expect trouble with
the parameters as such, more with the references.<br>
<br>
Is there a particular reason why you can't/don't want
to use ZSI? It's what e.g. vboxshell.py uses if one
selects the webservice. It gives a nice, direct python
object interface to the API, and can also talk to the
local API when it runs on the same system...<br>

<p class="xfmc6"><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>

</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>
