error: not xen image / you need to load the kernel first

[CamZie <camzie@xxxxxxxxxxxxxx>]

Hello,

We are having problems booting Ubuntu 20.04 installation with the newest kernel "5.4.0-156-generic" on our Ganeti (Xen) server.

We get the following error message everytime we boot the newest kernel:

       error: not xen image.
       error: you need to load the kernel first.

Using an older kernel "4.15.0-20-generic" works fine.

Ganeti (Xen) server:

• OS: Debian 11.7
• Ganeti version: 3.0.2-1~deb11u1
• Xen Hypervisor: 4.14.5+94-ge49571868d-1

Does anyone experience the same issue?

Thanks in advance.
