Move VM from UNRAID to Ubuntu/PiOS

[netfox]

Hello, All,

 

I'm planning to have a backup server on a Linux box or RPI.

 

How can I export the VM and use it on Ubutntu/PiOs/Debian?

 

Thank you

If you want to restore an image to a hd/sd card (bare metal):

I would restore the image to the hard disk/sd card with dd.

I would operate on the same pc booting from a live linux usb with the hard disk containing the vdisk and the empty hard disk/sd card.

The empty hard disk/sd card must be grater or equal in size than the size of the vdisk.

I would restore a raw image to the hard disk/sd card; if the image is in qcow2 format I would convert it to raw with qemu-img (you can do it in unraid):

qemu-img convert -f qcow2 -O raw /path/to/vdisk.qcow2 /path/to/save/vdisk.img

Then, use dd to restore the image:

sudo dd if=/path/to/vdisk.img of=/dev/sdX bs=10M

 

where sdX is the empty hard disk/sd card: this will restore all the partitions inside the vdisk image.

On the other hand, if you want to run the vdisk on another box in a vm, simply copy the vdisk image, create a new vm pointing to that vdisk.
