I have a computer running Windows 10 with VirtualBox 5.1.14. In this VirtualBox, I have 4 machines that are Linux. I always back-up these machines, like this: File -> Export Appliance; to import, I do: File -> Import Appliance.
Nowadays, I want to import a virtual machine to another computer. After importation made performed successfully, I started the machine, it shows an error: [image]

So, I appreciate the help.

This is a very old version of VirtualBox and is no longer supported. As a separate exercise, you may want to consider upgrading to 5.2.26 or 6.0.4 (the current versions as of writing).

I'm not sure what you used to take the image but cropping and resizing it to something smaller and more manageable would have been great!

To give any real guidance we are going to need the VBox.log file from the directory in the error dialog. Please ZIP it and attach it here.

Since you have a Windows 10 host, please use the "Snipping Tool" to grab screenshots in future.

Please post a VM log file. With the VM fully shut down, right click and "Show Log" in the GUI, save "VBox.log" (no other file) to a zip, and attach the zip here.

Sorry for the size of the picture, but I'm worried about the situation and I did not pay attention.
Sorry but I do not know what the file is. So, I'm putting two files together.

Incidentally, your method of creating backups does not actually create backups, it creates clones in a foreign format. The difference is that a clone is a working VM, but it isn't necessarily identical to the original VM (e.g. the disk format changes to VMDK, UUIDs will change), which a backup should be.

The recommended backup procedure is described here: FAQ: How to move a VM (backup of a VM is simply moving/copying the VM folder to secondary storage).

Regarding your error, your host seems to be very low on resources. 1325MB available, and you are allocating 1024MB+12MB graphics RAM to this VM. I don't think that is sustainable. I would reduce the main RAM allocation to 512MB, but I'd increase the graphics RAM to 48MB.

You should also fix this :-

00:00:02.439961 HM: HMR3Init: Falling back to raw-mode: VT-x is not available

Your processor is old (discontinued in 2010) but apparantly it does support VT-x. You need to enable it in the host BIOS.

I did not know this tool, I will use next time.
I needed to zip the file because it's bigger than 128kb.

I enabled this option in the host BIOS: Intel Virtual Technology. It worked!
So, I'd like to thank you. Thank you so much for your attention.

You're welcome, and thanks for reporting back.
