How to add an existing virtual disk to Proxmox

#

The first step is to place the disk image into the directory belonging to the virtual machine, on my system that would be /var/lib/vz/images//

Obviously the disk image should be in one of the formats supported by Proxmox, such as qcow2 or raw. Use qemu-img convert to convert between formats.

Next, go to Proxmox and check if the disk shows up under “Hardware” as an unused disk:

Converting between image formats

qemu-img convert: raw, qcow2, qed, vdi, vmdk, vhd

qemu-img convert -f raw -O qcow2 image.img image.qcow2

qemu-img convert -f vmdk -O raw image.vmdk image.img

VBoxManage: VDI (VirtualBox) to raw

VBoxManage clonehd ~/VirtualBox\ VMs/image.vdi image.img –format raw
