我试图在QEMU上替换Ubuntu 20.04中的linux内核(不确定QEMU是否相关(，但我得到了下一个错误：
INSTALL arch/x86/crypto/aegis128-aesni.ko
At main.c:160:
- SSL error:02001002:system library:fopen:No such file or directory: ../crypto/bio/bss_file.c:69
- SSL error:2006D080:BIO routines:BIO_new_file:no such file: ../crypto/bio/bss_file.c:76

make[1]: *** [scripts/Makefile.modinst:33: arch/x86/crypto/aegis128-aesni.ko] Error 1
make: *** [Makefile:1482: _modinst_] Error 2
我正在遵循以下步骤：
- 通过运行下一个命令创建一个新的空映像：
./qemu-img create -f qcow2 ../ubuntu-desktop-20.04.qcow2 60G
我创建60G是因为我们需要在QEMU中编译内核。
- 下载ubuntu ISO文件(https://ubuntu.com/download/desktop)。使用ubuntu-desktop20.04.qcow2和新的ubutnu ISO文件运行ubuntu：
build/qemu-system-x86_64 -cpu host -enable-kvm -boot d -m 2G -drive if=virtio,file=<full path to ubutnu image>/ubuntu-desktop-20.04.qcow2 -cdrom <full path to ubutnu iso>/ubuntu-20.04.2.0-desktop-amd64.iso
并安装ubuntu。我创建了用户名"；客人；以及密码"；1234"；
使用新安装的ubuntu:启动qemu
build/qemu-system-x86_64
-cpu host -enable-kvm
-m 16G
-vnc :0
-drive if=virtio,file=<full path to ubutnu image>/ubuntu-desktop-20.04.qcow2,cache=none
-device e1000,netdev=net0
-netdev user,id=net0,hostfwd=tcp::55556-:22
并通过vnc登录。启用ssh：安装ssh并永久启用：
sudo apt install ssh
sudo -s
systemctl enable ssh
exit
尝试使用ssh:进入
ssh guest@localhost -p 55556
你会得到下一个错误：
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
SHA256:kaSFtMxfTugjSHZJi1E1lCA5+GzBL5F8UuEQhgavVKo.
Please contact your system administrator.
Add correct host key in /home/yehuda.s/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /home/yehuda.s/.ssh/known_hosts:22
remove with:
ssh-keygen -f "/home/yehuda.s/.ssh/known_hosts" -R "[localhost]:55556"
ECDSA host key for [localhost]:55556 has changed and you have requested strict checking.
Host key verification failed.
运行下一个命令：
ssh-keygen -f "/home/yehuda.s/.ssh/known_hosts" -R "[localhost]:55556"
然后再次尝试ssh。
安装：
sudo apt-get install build-essential libncurses-dev bison flex libssl-dev libelf-dev
下载所需的内核(可以从https://www.kernel.org/)进入qemu。我下载了5.12.13。cd放入下载的文件夹并提取文件：
tar -xvf linux-tar.xz
cd到linux-5.12.13中，并将当前ubutnu内核的配置复制到以下文件夹中：
cp -v /boot/config-$(uname -r) .config
在从/boot复制的.config文件中，找到config_SYSTEM_TRUSTED_KEY和config_MODULE_SIG_KEY行，并删除它们的值(留空"(。
运行：
make menuconfig #- and config this as you want (I did nothing)...
make -j
make modules_install
我看到：https://www.reddit.com/r/linuxquestions/comments/byinth/cannot_stat_archx86cryptoaegis128aesniko_no_such/和https://unix.stackexchange.com/questions/389484/aes-x86-64-ko-no-such-file-or-directory-for-module-installation-failure-after-4#389511错误，并尝试了他们的建议-但它不起作用
解决了它。。。运行后
cp -v /boot/config-$(uname -r) .config
需要运行
make localmodconfig
按回车键获取所有默认值，然后继续
make
sudo make modules_install
sudo make install
