Decompression happens on provisioning

[AbdelrahmanElawady]

Describe the bug

Decompression happens on provisioning not running the VM. So, when rebooting a VM with new kernel installed inside it, it won't work if it is compressed. Which shouldn't happen.

To Reproduce

• Run a VM with kernel in it like this
• Install a new kernel (apt install linux-image-<version> or a script like this).
• Reboot the VM
• It won't boot again and the workload will be deleted.

Expected behavior

To be decompressed and the image to boot up again.
