How to Migrate from VirtualBox to QEMU?

Moving virtual machine (VM) images from one hypervisor to another is a necessary step in the migration from VirtualBox to QEMU. We can run VMs on the PC using both VirtualBox and QEMU, but they require different setups and file formats. Let’s look into the steps:

1. Close the VirtualBox virtual machine. Also, verify the easy access of the virtual machine files.

2. Disk images in the QCOW2 format are commonly used by QEMU, whereas VirtualBox uses custom formats such as VDI or VMDK. The VM’s disk image needs to be converted to QCOW2 format. For this, we can make use of programs like qemu-img.

3. From VirtualBox, copy the VM settings. This may involve setups for the CPU, RAM, network, etc. We can also use QEMU to recreate the VM by exporting the setup. We must carefully review the VirtualBox setup and copy the corresponding parameters in QEMU.

4. Using the exported settings and the converted disk image, then, create a new VM in QEMU. The setup, as well as control of VMs, can be done with QEMU commands or programs like virt-manager or virsh.

5. Now, we must make some adjustments to the parameters to match the original VirtualBox setup after the VM has been created in QEMU. This could involve assigning devices, setting up networks, etc.

6. In order to confirm that the process was successful, run the VM in QEMU to assess how it works. Make sure that every program and service operating within the VM is performing as planned.

7. After confirming that the transition to QEMU has gone well and VirtualBox is no longer needed, we can remove it from the computer to free up space and prevent problems.

Conclusion

Although QEMU and VirtualBox are both hypervisors, their features, setups, and performance traits differ. In order to optimize the migrated VM for QEMU, a few changes may therefore be needed.
