I just did so, and ended up no longer beeing able to boot to GUI.
After beeing stuck after the plymouth-screen (Fedora) it stucked between init 3 & init 5, somewhere...

Changing the GRUB command line helped to enter multi-user stage.
But even with deleting the just added MOK (during & after restart), i just once could boot to GUI, thought it was stable and never achieved again until i reinstalled my system just now.

Bad first experience i guess Smilie

Also, since i first installed such a signed key, when recreating grub2 config, it spawned some errors like:
Code:
ERROR: sil: invalid metadata checksum in area 3 on /dev/dm-0

But since this still happends, me not sure what it caused initaly...

System: 3.17.7-300.fc21.x86_64
I had used the attached script to sign the keys, which i just worked on, and now going to test for real again...
Now that the system was just installed this evening i dont have much to "loose" anyway.. Smilie

<3 custom LiveSpin's Smilie

Any ideas what i did wrong?
Thank you in advance and good night - wish me luck.

NAME
libguestfs-test-tool - Diagnostics for libguestfs SYNOPSIS
libguestfs-test-tool [--options] DESCRIPTION
libguestfs-test-tool is a test program shipped with libguestfs to allow you to check basic libguestfs functionality is working. This is needed because libguestfs occasionally breaks for reasons beyond our control: usually because of changes in the underlying qemu or kernel packages, or the host environment. If you suspect a problem in libguestfs, then just run: libguestfs-test-tool It will print lots of diagnostic messages. If it runs to completion successfully, you will see this near the end: ===== TEST FINISHED OK ===== and the test tool will exit with code 0. If it fails (and/or exits with non-zero error code), please paste the complete, unedited output of the test tool into a bug report. More information about reporting bugs can be found on the <http://libguestfs.org/> website. OPTIONS
--help Display short usage information and exit. --qemu qemu_binary If you have downloaded another qemu binary, point this option at the full path of the binary to try it. --qemudir qemu_source_dir If you have compiled qemu from source, point this option at the source directory to try it. -t N --timeout N Set the launch timeout to "N" seconds. The default is 600 seconds (10 minutes) which does not usually need to be adjusted. -V --version Display the libguestfs version number and exit. TRYING OUT A DIFFERENT VERSION OF QEMU
If you have compiled another version of qemu from source and would like to try that, then you can use the --qemudir option to point to the qemu source directory. If you have downloaded a qemu binary from somewhere, use the --qemu option to point to the binary. Note when using these options, you can ignore the business of qemu wrapper scripts ("QEMU WRAPPERS" in guestfs(3)), since libguestfs-test- tool writes a wrapper script for you if one is needed. TRYING OUT A DIFFERENT KERNEL
If you are using febootstrap >= 3.8 then you can select which kernel libguestfs tries. You do this by setting the environment variables "FEBOOTSTRAP_KERNEL" and/or "FEBOOTSTRAP_MODULES". Refer to "ENVIRONMENT VARIABLES" in febootstrap-supermin-helper(8) for further information. SELF-DIAGNOSIS Refer to "APPLIANCE BOOT PROCESS" in guestfs(3) to understand the messages produced by libguestfs-test-tool and/or possible errors. EXIT STATUS
libguestfs-test-tool returns 0 if the tests completed without error, or 1 if there was an error. ENVIRONMENT VARIABLES
For the full list of environment variables which may affect libguestfs, please see the guestfs(3) manual page. SEE ALSO
