Encrypting boot partition Libvirt not showing the OS booting up

[john doe]

Hi,

I have installed Debian Buster with encrypted LVM so apon installation
my root partition is encrypted.
So far so good but as soon as I encrypt the boot partition, after reboot
the OS won't start.
If I start the drive directly with qemu, it works but it looks like
Libvirt is somehow not able to deel with it.

What am I missing?
