Hi,
I have a quick question. How do we add a hard disk to the qemu ARM VM?
I tried:
qemu-system-aarch64 -machine virt -hda disk.img -kernel image -initrd initrd.img
qemu-system-aarch64 -machine virt -sd disk.img -kernel image -initrd initrd.img
qemu-system-aarch64 -machine virt -mtdblock disk.

The side effect is that the hash function is changed, the current
way is:
gfn & ((1 << KVM_MMU_HASH_
After commit 77b0f5d (KVM: nVMX: Ack and write vector info to intr_info
if L1 asks us to), "Acknowledge interrupt on exit" behavior can be
emulated. To do so, KVM will ask the APIC for the interrupt vector if
during a nested vmexit if VM_EXIT_ACK_INTR_ON_EXIT is set. With APICv,

External interrupt will cause L1 vmexit w/ reason external interrupt when L2 is
running. Then L1 will pick up the interrupt through vmcs12 if L1 set the ack
interrupt bit. Commit 77b0f5d (KVM: nVMX: Ack and write vector info to intr_info
if L1 asks us to) get intr that belongs to L1 before load v
