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:

diff --git a/hw/arm/virt.c b/hw/arm/virt.c
index b871350856..de11ff51d1 100644
--- a/hw/arm/virt.c
