LINODE的KVM架構LINUX更換內核 文章转载自：Madlax的杂物房（http://madlax.pw/） http://madlax.pw/2016/12/03/103.html

安裝Grub 安裝過程中可能會詢問安裝位置，不需要安裝到MBR

Arch Linux

pacman -S linux grub

CentOS 7

yum install kernel grub2

Debian

apt-get install linux-image-amd64 grub2

Fedora 22

dnf install kernel-core grub2

Ubuntu

apt-get install linux-image-virtual grub2

配置Grub

編輯/etc/default/grub，修改以下項目：

GRUB_TIMEOUT=10

GRUB_CMDLINE_LINUX="console=ttyS0,19200n8"

GRUB_DISABLE_LINUX_UUID=true

GRUB_SERIAL_COMMAND="serial --speed=19200 --unit=0 --word=8 --parity=no --stop=1"

GRUB_TERMINAL=serial

更新bootloader，更新內核後需要再一次運行該命令來更新GRUB目錄，

預設為清單第一個內核啟動：

Arch Linux

grub-mkconfig -o /boot/grub/grub.cfg

Debian 8 & Ubuntu 15.04

update-grub

CentOS 7

mkdir /boot/grub

grub2-mkconfig -o /boot/grub/grub.cfg

Fedora 22 - Replace with the current kernel version

dracut /boot/initrd-4.0.5-300.fc22.x86_64.img 4.0.5-300.fc22.x86_64

mkdir /boot/grub

grub2-mkconfig -o /boot/grub/grub.cfg

重啟到Grub2 模式

在LINODE面板選擇編輯你的設定檔

Click on Edit under the Configuration Profiles section

在Boot Settings選項的Kernel清單裡選擇GRUB 2

In the Boot Settings section, select GRUB 2 from the Kernel drop down menu

點Save Changes保存，重啟機子後就可以按通常方式更換發行版本內核了。

啟動中可能會出現以下錯誤，可以忽略。

error: file `/boot/grub/i386-pc/all_video.mod' not found.
