Hi Klaus,
Thank you again. One more question. Is it possible to get the Virtual
Machine pop-up in my windows machine hosting vm after clienttest.pl
startvm <vm>?
I believe in need to put gui somewhere in below line. But I don't know
where.
my $progress = vboxService->IMachine_launchVMProcess($machine,
$session,
"vrdp",
"");
Regards,
Rajiv

That one was renamed to ISession_unlockMachine
