It's all in the title, for no reason Mac OS crashed while one of my vm was running. After turning my computer back on again, I can't turn this vm on again, the following error is displayed.

Code: Select all

Could not open the medium '/Users/my_login/VirtualBox VMs/Kali-Linux-2018.3-vbox-amd64/Kali-Linux-2018.3-vbox-amd64-disk1.vmdk'.

I tried several things like disabling NAT, then renamed some prev files but without a solution. Thank you in advance for your help

The crash has caused a corruption of the .vmdk disk image file. No amount of tinkering with network or other unrelated settings is going to fix that.

The vmdk isn't a native VirtualBox disk image format (.vdi). You will need to download the command line tools from VMWare and run the vmware-vdiskmanager utility to repair the .vmdk file and then VirtualBox should be able to load it again.

I have never used the tool so don't know if there is a macOS version of it or whether you will have to copy the broken .vmdk file to a Windows / Linux machine and use the tool there and then copy the repaired file back again.

All right, thanks for your answer, I'll look this way then

However if some of them have software to recommend for mac I'm a taker, apart from setting up a vm windows I don't have any on hand
