Vbox removes devices to early

[Megachip]

Every time, I'm changing settings of the box while running, it throws out mounted devices (usb, sata etc.).

OSX immediately taken these devices and remount them on host device, so the box will crash cause it has no access to the devices anymore.

Same happens pushing the close button (after what the interface ask for shutdown, pause or power off). Devices will be ejected and can't remounted if I cancel the dialog.

Happens on 5.0.0 RC1 too.

Please upload a VBox.log from the affected VM, the VBox version the log is from doesn't matter.

Crash after inserting guest additions

[Megachip]

Possible it matches https://www.virtualbox.org/ticket/9975 too. It did not matter if it is sata, ide or usb.

This bug is really nasty. Occurred in 5.0.0 too.

Inserting guest additions iso into VirtualBox and it crashed.

Crash after inserting guest additions

[aeichner]

We know what the issue is which causes the remount but it is a bit difficult to fix. This bug will be fixed in one of the maintenance releases.

[aeichner]

This will be fixed in the next maintenance release. VBox now tries to unmount all used volumes before opening and denies any mount attempt on the host while the VM is running. I uploaded a testbuild to https://www.virtualbox.org/download/testcase/VirtualBox-5.0.1-101955-OSX.dmg for you to try out. Would be great if you could verify that the issue is fixed now, thanks!

[Frank Mehnert]

Fix is part of VBox 5.0.2. Please reopen if necessary.
