Create VM using pre-baked qcow2

[FaZ]

I am trying to create a VM on Proxmox 4 using one of the qcow2 images from cloud.centos.org/centos/7/images/

Is there a recommended way to do it? It's not possible from the Proxmox web GUI.

Create a dummy qcow2 disk in the GUI attached to the VM. Then remove from the VM. In the CLI, 'mv' the qcow2 image you want to use on top of the dummy one. In the GUI, re-attach the 'unused' qcow2 disk to the VM. I've done something like this...

you can use pvesh. for example,

cp image.qcow2 /mystorage/vm-$vmid-disk-1.qcow2
pvesh set /nodes/$node/qemu/$vmid/config -scsi0 mystorage:$vmid/vm-$vmid-disk-1.qcow2,cache=writeback

$node is the name of that proxmox host. storage types other than "dir" will use $vmid-disk-N, without the "vm-" in front. see the api, https://pve.proxmox.com/pve-docs/api-viewer/index.html for details.

Thanks for your replies.

PVE 5.0 will include a tool to import external disk images to an existing VM.
So you will be able to do

qm create 501
qm importdisk 501 my_qcow2 my_storage_id

the disk will appear then as "unused disk" in the gui, and you then attach the disk to a virtio blk, sata or scsi controller
