I cannot take a snapshot: Spurious error from VirtualBox

[Paddy Landau]

AFAICS, this behavior is not configurable, so you'd have to modify the VirtualBox source code and build it yourself.

Yeah, I don't have the time to mess around with that!

As an easy test, you could try to circumvent the problem by using a VM with a legacy BIOS (no .nvram file needed) ...

I just tested this, and you're right, it works. However, I'm not going to rebuild my existing VM — it's Windows and you know how long that takes!

I'm going to take a completely different approach. Create a script that:

• starts at boot time running under root
• watches the required folder using inotifywait
• sets full access to all files whenever it sees a change (watching out for race conditions)

Thank you again for all your hard work. Many people have tried to create a shared VM according to what I've found on the internet, so if I can find out how, I'll submit a request to Oracle to allow this.

Same error as Paddy.
In my case i solved it disabling the 'Enable EFI (Special OSes only)' option
That allow me to take a snapshot correctly.
After that, i switched back to work again with the guest.
