How to import a Virtualbox image


In this example we have VirtualBox machine called EXAMPLE.

Create an empty Virtual Machine

From the Ravada admin form, create a new virtual machine with the same operative system as the one installed in the virtual box machine.

Do not install anything in that machine, keep it off. Check what is the name of the disk volume and remove the other volumes.

Check the contents file attribute with the command virsh edit EXAMPLE,

source file='/var/lib/libvirt/images/EXAMPLE-vda-id8Q.img'/

Remove the swap, cdrom and other disk volumes.

This is the SWAP volume, notice its name ends in .SWAP.img.

<disk type='file' device='disk'>
  <driver name='qemu' type='raw' cache='none'/>
  <source file='/var/lib/libvirt/images/EXAMPLE-aGam.SWAP.img'/>
  <target dev='vdb' bus='virtio'/>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/>

This is the cdrom disk drive, remove it too.


Remove also the SWAP image file:

$ sudo rm /var/lib/libvirt/images-celerra1/EXAMPLE-_G_m.SWAP.img

Convert the image file

Make sure the VirtualBox machine is down, then convert the VDI to raw, then to qcow2


$ qemu-img convert -f vdi -O qcow2 EXAMPLE.vdi EXAMPLE.qcow2


1. Convert to raw

$ VBoxManage clonehd --format RAW EXAMPLE.vdi EXAMPLE.img

2. Convert to qcow2

Convert to qcow2 using the name you saw before in the XML definition of the machine:

$ sudo qemu-img convert -f raw EXAMPLE.vdi -O qcow2 /var/lib/libvirt/images/EXAMPLE-vda-id8Q.img
