问题原因：qemu仿真默认内存大小128M不够，需要手动配置下，加参数 -m 512， 如下所示：
qemu-system-aarch64 -M virt-4.0 -cpu cortex-a57 -nographic -m 512 -kernel Image-5.10.0 -initrd openeuler-image-qemu-aarch64-20220803102612.rootfs.cpio.gz -device virtio-9p-device,fsdev=fs1,mount_tag=host -fsdev local,security_model=passthrough,id=fs1,path=/ --append "console=ttyAMA0 rdinit=/linuxrc"
