Conversion from KVM qcow2 (from proxmox) to Virtualbox VDI

June 11, 2013 Leave a comment

Method 1:

Convert first from qcow2 to RAW using qemu-utils in an Ubuntu Linux machine

sudo apt-get install qemu-utils
qemu-img convert -f qcow2 <qcow2_VM_filename> -O raw <RAW_file_VM_filename>

Convert from RAW to VDI using VBoxManage on any machine that has Virtualbox Installed

VBoxManage convertfromraw <RAW_file_VM_filename> <VDI_Output_file_VM_filename> \ 
--format vdi

The “\” is just a line-break because the command doesn’t fit in one line on this page

Method 2:

Use qemu-img directly in a Linux machine:

qemu-img convert -f qcow2 <qcow2_VM_filename> -O vdi <RAW_file_VM_filename>

NB: For some strange reason Method 1 worked once and failed the 2nd time, Method 2 was always successful. So i suggest using Method 2
