What am I doing wrong?

Versions of the related components and OS (frontend, hypervisors, VMs):
Ubuntu Server 22.04. Opennebula 6.6. Firecracker node.

Looks like the kernel image is having issues while being transferred from the IMAGE datastore to the SYSTEM datastore. Re-read/Re-check this section and also the image contents.

Thanks!!! I forgot to create the KERNEL_DS! :sweat_smile:

Edit:

Now I have a new problem, the LCM STATE is “RUNNING”, but the vnc access gives me a black screen. Is it normal behavior for a MicroVM? After a few minutes it shows “CLIENT_ERROR”.
