Installed the latest Alpine image for VMs:

At least the second log looks like you're using a kernel without kexec support?

https://wiki.alpinelinux.org/wiki/Kexec tells you how to check

[Mic92]

The first error message is also weird because kexec-tools doesn't use memfd itself, so it is happening in the kernel.
