我所运行的qemu命令为: qemu-system-x86_64 -smp 1 -machine q35 -cpu Haswell,+smap,-check,-fsgsbase -m 1G -serial mon:stdio -serial file:serial.out -drive format=raw,if=pflash,readonly=on,file=/storage/emulated/0/OVMF.fd -drive format=raw,file=fat:rw:/storage/emulated/0/xinhao/windows/esp -nic none -netdev user,id=net1,hostfwd=tcp::8000-:80,hostfwd=tcp::2222-:2222,hostfwd=udp::6969-:6969 -device e1000e,netdev=net1 -display none

x86 我不怎么了解，不过可能提供一下你怎么编译的镜像会有帮助，有一些跟 pci 有关的 feature

[fish4terrisa-MSDSM]

Kernel: cd ./zCore make build ARCH=x86_64 LINUX=1

[fish4terrisa-MSDSM]

rootfs&image: cargo rootfs --arch x86_64 cargo image --arch x86_64

[shzhxh]

make build ARCH=x86_64 LINUX=1

可以使用make run ARCH=x86_64 LINUX=1试试，可以检查一下对应的esp目录下是否有x86_64.img文件

[fish4terrisa-MSDSM]

有x86_64.img文件，我用的是那个命令，不过因为我编译服务器上没有qemu所以是复制了那个命令在电脑上执行

[shzhxh]

请提供一下相关的文件，包括/storage/emulated/0/xinhao/windows/esp和/storage/emulated/0/OVMF.fd。

[fish4terrisa-MSDSM]

esp.zip

OVMF.fd.tar.gz

[fish4terrisa-MSDSM]

就是这两个诶

[shzhxh]

你的esp/EFI/Boot/rboot.conf文件里initramfs=\EFI\zCore\ini.img给注释掉了，把它取消注释应该就好了。

[fish4terrisa-MSDSM]

抱歉。发错了，那个是我之前的一个错误，后来我已经解决了。 esp.tar.gz 因为一个是zip一个是tar所以拖动错了，抱歉

[fish4terrisa-MSDSM]

要么你把我那个解压了然后用qemu试一下应该就能看到了

[shzhxh]

rboot.conf里initramfs=\\EFI\\zCore\\x86_64.img应改为initramfs=\EFI\zCore\x86_64.img

[fish4terrisa-MSDSM]

ok，解决了，多谢(这一错误是在反复编译中诞生的)
