Hi,
I want to improve the startup speed of Windows VM. On the x86
architecture, QEMU's Windows11 VM can enable the Fast startup function,
but it cannot work on the ARM architecture. By the way, the Fast startup
function of Windows on ARM physical machines can work normally.
Is there anything missing in QEMU's ARM architecture for Windows guest?
My environmental information:
Linux 5.10
QEMU 6.2.0
Guest: Windows11 ARM
QEMU command line:
qemu-system-aarch64 -nodefaults -machine
virt,kernel-irqchip=on,virtualization=off,gic-version=3,its=off -accel
kvm -cpu host -m 6144 -smp 6 -bios
/usr/share/edk2/aarch64/QEMU_EFI-pflash.raw -drive
if=none,id=system,format=qcow2,file=/data/images/win11_disk.qcow2
-device virtio-blk-pci,drive=system -device
nec-usb-xhci,msix=off,msi=off -device usb-kbd -device usb-tablet -device
ramfb -display gtk -name Windows -qmp unix:/tmp/qmp.socket,server,nowait
-d all -D /tmp/qemu.log -msg timestamp=on
Refer to the Fast startup link below:

Thank you.
