UnmountToolsInstaller does not return until a humain answer the VM

[mathieu182]

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.

@mathieu182 what version of vSphere are you using where it hangs waiting for the question? Also not sure if it matters but what version of container hardware do you have selected for the VM?

Hello,
I'm using vSphere version 5.1.0. About your second question, I'm not sure I've correctly understood. The storage is a RAID 1 disk with HP SAS, partition VMFS5

@mathieu182 UnmountToolsInstaller() on vSphere v5.5 waits as well until the question is answered. I had to pull the question from vim.VirtualMachine.runtime.question and answer it. Pretty sure it is the way the vSphere API is designed.

@jm66 I cant seem to find vim.VirtualMachine.runtime.question available in the documentation at https://github.com/vmware/pyvmomi/tree/master/docs ...

But I found https://github.com/vmware/pyvmomi/blob/master/docs/vim/vm/QuestionInfo.rst ...

How would I answer this question? Do you happen to have an example by any chance?

Cheers
