qemu-system-aarch+win11arm

I compiled a set of qemu+libvirt under arm, and then used virsh to import and open the pre-prepared win11_arm.xml and the corresponding win11_arm.qcow2. The host machine is the Kylin system, and the virtual machine installed is Windows 11 arm. However, when I first started the virtual machine, I always found that the timing was incorrect.I need some ideas. Thank you!!!
