本文以PVE7.0-13为例

首先推荐一下大佬的github

yfdoor/PVE-Kernel: Compile PVE-Kernel for IOMMU Group (YFDOOR) (github.com)

1、准备好内核

先进入大佬的github项目页，切换到分支，会git的就git，不会git的就下载zip

 

 

 

切换分支之后，点击下载zip就可以下载

 

 

2、安装内核

将内核放置到pve主机下的一个目录，如我的是/root下面

root@pve2:~/PVE-Kernel# ls
pve-kernel-5.13.14-1  pve-kernel-5.13.18-1  README.MD
root@pve2:~/PVE-Kernel#

注意这里有2个文件夹，对应着不同的内核版本。自己选择一个就行，建议还是选择新内核

进入新内核文件夹，可以看到有多个deb文件。这些就是破解后的内核文件。

root@pve2:~/PVE-Kernel/pve-kernel-5.13.18-1# ls
linux-tools-5.13_5.13.18-1_amd64.deb	       pve-kernel-5.13.18-1-pve_5.13.18-1_amd64.deb
linux-tools-5.13-dbgsym_5.13.18-1_amd64.ddeb   pve-kernel-libc-dev_5.13.18-1_amd64.deb
pve-headers-5.13.18-1-pve_5.13.18-1_amd64.deb

使用命令

dpkg -i *.deb

开始安装内核。

正常的情况如下，如果不是，请注意！不要继续。

内核安装完成之后，在grub文件里添加一个参数pcie_acs_override=downstream

grub如下

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on  pcie_acs_override=downstream"
GRUB_CMDLINE_LINUX=""

随后进行保存，并且更新内核，更新grub

update-grub
update-initramfs -k all -u

随后重启

3、验证

使用命令验证

for d in /sys/kernel/iommu_groups/*/devices/*; do      n=${d#*/iommu_groups/*}; n=${n%%/*};     printf 'IOMMU Group %s ' "$n";     lspci -nns "${d##*/}"; done;

我的输出如下

root@pve2:~/PVE-Kernel/pve-kernel-5.13.18-1# for d in /sys/kernel/iommu_groups/*/devices/*; do      n=${d#*/iommu_groups/*}; n=${n%%/*};     printf 'IOMMU Group %s ' "$n";     lspci -nns "${d##*/}"; done;

    这个怎么破，文件放到root下面了

    内核版本比修改版高的也可以吗？

      只要符合pve版本的内核都可以，例如pve7,那么使用5.13，5.15都可以。

    写的很好，不过补充一点，当使用的pve版本大于博主(7.0-13)时，内核启动是优先版本最新的，需要手动切换内核启动顺序
    方法如下：
    grep menuentry /boot/grub/grub.cfg 检查启动顺序
    看到名为"Advanced options for Proxmox VE GNU/Linux"的二级菜单下有"Proxmox VE GNU/Linux, with Linux 5.13.18-1-pve"的内核

    vim /etc/default/grub中修改
    GRUB_DEFAULT="1>2" #（数字为启动项顺序）
    或者
    GRUB_DEFAULT="Advanced options for Proxmox VE GNU/Linux>Proxmox VE GNU/Linux, with Linux 5.13.18-1-pve"

    update-grub
    reboot

    第二种方法是pve重启后会有个启动界面，选择第二个再选择新安装的自定义内核
