This is a great patch, thanks.
Since you have investigated and got some knowledge, could you help
explain what is host protected virtual machines on s390? What is the
difference between normal kvm guest on x86_64/arm64 and this on s390?
Thanks

requires a minimum of ~2.5GB memory and thus exceeds what is
typically
reserved for the crashkernel. Thus remove "prot_virt" from the command
line for the 2nd kernel to prevent it to run out-of-memory.
