[solved] Can't start VB, NS_ERROR_FAILURE (0x80004005)

[Androix]

Hello everyone

Currently I'm trying to start VB but it doesn't work. An hour ago I was able to start it but because of another issue (the network folders couldn't be opened and are still disconnected) I had to restart my system. I did it twice but nothing happend, so I also ended the VB-processes with the system monitor. Now the following error message occured:

The selected virtual machine is inaccessible. Please inspect the error message shown below and press the Refresh button if you want to repeat the accessibility check:

Runtime error opening '/media/drives/Windows 10/Windows 10.vbox' for reading: -138(Device or resource is busy.).
/home/vbox/vbox-5.0.2/src/VBox/Main/src-server/MachineImpl.cpp[736] (nsresult Machine::i_registeredInit()).
Result Code:
NS_ERROR_FAILURE (0x80004005)
Component:
MachineWrap
Interface:
IMachine {f30138d4-e5ea-4b3a-8858-a059de4c93fd}

What do I have to do to make it work again?

Regards

Reboot. Host and guest.

Thank you for your help, socratis. Finally my boyfriend was able to solve the problem which was caused by a faulty network folder. By that I was also unable to connect the other network folders.

That's not what the error was talking about, unless you have placed the VM in a network drive, in which case the networked .VBOX file could not be found. Yeah, that would make sense...
