I am trying to get QEMU/KVM to run on ubuntu 19.10 but when starting the virtual machine (Windows 10) it freezes the complete system (guest and host). I was suspecting that this is because the
linux-kvm package was not installed.
I installed the package and the dedicated kernel
When trying to boot this kernel I get
error: /boot/vmlinuz-5.3.0-1004-kvm has invalid signature
Assuming the kernel not to be signed, I tried to sign it using this tutorial. Result:
sbsign --key MOK.priv --cert MOK.pem /boot/vmlinuz-5.3.0-1004-kvm
Invalid DOS header magic
Pretty confused I tried one last thing and turned off secure boot. It would still give me the invalid signature after reboot.
Any further input what I could do?
