qemu-img create -f qcow2 -b win10-arm64-gold.qcow2 vm1.qcow2 All VMs share the base image. Writes go to the overlay. | Problem | Likely Cause | Solution | |---------|--------------|----------| | QEMU crashes on start | Missing UEFI firmware | Ensure QEMU_EFI.fd is correct for ARM64, not x86. | | Blue screen: INACCESSIBLE_BOOT_DEVICE | No VirtIO driver during install | Use if=ide for the ISO and switch to virtio after driver install. | | Extremely slow GUI | No GPU acceleration | Add -device virtio-gpu-pci . On Linux, add -display sdl,gl=on . | | QCOW2 ballooning to full size | No TRIM support | Run the guest-side TRIM command and use discard=unmap . | | Keyboard/mouse not working | Missing USB controller | Add -device qemu-xhci -device usb-kbd -device usb-mouse . |
