[SOLVED] Can't get working ubuntu cloud images.


Mar 10, 2019
Hi, I wanted to try out ubuntu cloud images by following this documentation. https://pve.proxmox.com/wiki/Cloud-Init_Support
However 4th command is not working.

# download the image
wget https://cloud-images.ubuntu.com/bionic/current/bionic-server-cloudimg-amd64.img

# create a new VM
qm create 9000 --memory 2048 --net0 virtio,bridge=vmbr0

# import the downloaded disk to local-lvm storage
qm importdisk 9000 bionic-server-cloudimg-amd64.img local-lvm

# finally attach the new disk to the VM as scsi drive
qm set 9000 --scsihw virtio-scsi-pci --scsi0 local-lvm:vm-9000-disk-1

When I run this command qm set 9000 --scsihw virtio-scsi-pci --scsi0 local-lvm:vm-9000-disk-1 it gives error: can't get size of '/dev/pve/vm-9000-disk-1': Failed to find logical volume "pve/vm-9000-disk-1"

How can I make it work? Thank you. Actually someone reported this issue earlier here. But looks like no one solved it.
Got it working by luck. If I run this command 2 times, it works.

Found the reason of it.

qm set 9000 --scsihw virtio-scsi-pci --scsi0 local-lvm:vm-9000-disk-1

should be

qm set 9000 --scsihw virtio-scsi-pci --scsi0 local-lvm:vm-9000-disk-0. Reason why this worked when I ran the command 2 times, it creates disk-0 at first run and disk-1 at second run thus resulting success.

So creating disk-0 would be correct command.
