add to kvm :

update VM 592: -virtio2 /dev/disk/by-id/ata-ST3000DM001-1CH166_Z1F41BLC

check:

grep Z1F41BLC /etc/pve/qemu-server/592.conf

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/<id>/

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
