I try to restore the snapshot of a Saved/PowerDown machine but fail.
The VM has a snapshot called 'snapshot' before it's powered on. The VM has
been
powered on by IVirtualBox::openRemoteSession().
<code>
// 'manager' is a IWebSessionManager objec
// 'vbox' is a IVirtualBox object
ISession session = manager.getSesscionObject(vbox);
// machine
vbox.openExistingSession(session, machine.getId());
ISnapshot snapshot1 = machine.findSnapshot("snapshot1");
IProgress progress = session.getConsole().saveState();
progress.waitForCompletion(-1);
long result = progress.getResultCode();
session.getConsole().restoreSnapshot(snapshot);
<code>
Error from vboxwebsrv.exe:
API return code: 0x80BB0002 (VBOX_E_INVALID_VM_STATE)
COM error info result code: 0x80BB0002
COM error info text: The virtual machine is being powered down
Several notes:
* Even if I do powerDown() instead of saveState(),restoreSnapshot() still
fails.
* I call ISession::getState() before restoreSnapshot(), and it's CLOSED.
This confuse me. The documentations says restoreSnapshot() cannot be
executed on a running machine, so I power it down first, but after powering
down, the session is *closed*, meaning that I cannot use the session object
to restore the snapshot.
* I notice that phpvirtualbox doesn't use IWebSessionManager and neither
openRemoteSession(). Instead it uses openSession() to open a direct session.
I cannot do this since I am doing every operations remotely instead of
writing a
frontend.
