UnmountToolsInstaller does not return until a humain answer the VM

Hiya,

I'm trying to mount and unmount vmtools using:

MountToolsInstaller()
UnmountToolsInstaller()

However I've sometimes a VM question to answer, right after the UnmountToolsInstaller() call, like this one:
"The guest operating system has locked the CD-ROM door and is probably using the CD-ROM, which can prevent the guest from recognizing media changes. If possible, eject the CD-ROM from inside the guest before disconnecting. Disconnect anyway and override the lock? (yes/no)"

As the UnmountToolsInstaller() returns none, I cannot answer the VM as it's done with powerOn for instance. Moreover, the application waits for UnmountToolsInstaller() to return, which happens only when someone answer the question.

So I'm wondering if it's a design issue or if I'm not using pyvmomi the proper way. Any help / feedback would be greatly appreciated.

Thanks.

Start by tracing MountToolsInstaller() and UnmountToolsInstaller() in pyvmomi and compare their return behavior with powerOn. Reproduce the VM prompt scenario and determine how the API currently handles the blocked unmount; done should define a way for callers to observe or respond to that interaction without waiting indefinitely.
