When following this guide on a host not capable of native arm64 KVM, replace -M virt -cpu host -accel kvm with -M virt,virtualization=on -cpu max.

The reason for virtualization=on is that the Windows bootloader does an smc #0 PSCI call, but without EL2, QEMU's TCG does not handle those because PSCI is in HVC mode and such that instruction is treated as undefined. With KVM enabled, smc #0 is handled properly.

Workaround in QEMU for using TCG without virtualization=on:

void setValue(int v);
extern int value;

int main()
{
        setValue(42);
        return value;
}
