5.2.20 Linux Host Issue _Will Not Boot

[mcuser]

I upgraded my Mac to Mojave and also upgraded VirtualBox to 5.2.20 r125813, and installed the current extension pack. When I boot my Linux VM, I get a black screen with a blinking curser. I am using OEL Linux LinuxOBI-7.2.64.1

Thanks

We need to see a complete VBox.log, from a complete VM run:

• Start the VM from cold-boot (not from a paused or saved state) / Observe error / Shutdown the VM (force close it if you have to).
• With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
• Save only the first "VBox.log", ZIP it and attach it to your response. See the "Upload attachment" tab below the reply form.

VBox.log uploaded.

Thanks

Did you install this VM yourself, or did you import it from someplace? Given the virtual hard drive name, I suspect that you imported the VM. If yes, where from?

I did import it, I downloaded it from MyDesktop, Linux OBI. This was working before upgrading my Mac and upgrading Virtualbox. I imported the VM again and it booted the first time before I installed the guest additions, after that I got the same black screen and blinking curser.

Thanks

Do you have a link for the download? You can either obfuscate it (e.g. www virtualbox org) or include it in a text file and attach the text file. I'll edit your message to deobfuscate the link.

Socrates,

I sent you a PM.

Thanks

Socrates,

There is not an external link for this OS. Did you see anything in the log file?

Thanks

As I told you in the reply PM:

Especially an OVA, i.e. a pre-made VM, it's really difficult to troubleshoot without recreating it, only its creator knows what it's installed (or not) in there...

Which, to put it in other words, is similar to me building a PC, and you bringing me a hard disk with an unknown OS/settings and you're telling me it's not booting...
