Compile a Linux 3.1.0 kernel that supports xen

Document directory

• Processor types and features -->

This is my first time to fully compile the Linux kernel ...... However, starting from the higher version, many problems in the old kernel have been fixed by developers, but they are easier. Add xen support to the kernel.

From version 2.6.39, the kernel can support xen dom0 and domu directly without patches.But it is not easy to change the xen-related compilation options. Maybe I am not used to the kernel compilation method.

Environment: gcc4.5 processor Pentium D e2140 (the old processor does not support hvm and can be used together)

After downloading the Linux 3.1.0 kernel, sudo make menuconfig enters the configuration screen.

1. Configuration

Processor types and features --> Processor family selects Pentium 4 (the highest value is selected based on the actual situation. The old processor cannot)

The maximum memory size of the high memory support below is 64 GB,In this case, a hidden option is displayed:

PAE supportThis option is automatically selected.

Go to paravirtualized guest support, and a hidden option is displayed.

Xen guest support(=) Select!

The compiled kernel can be either dom0 or domu. The kernel automatically adapts.

Finally, let's take a look at other options to remove the AMD processor.

2. Installation

After configuration, make or

sudo make -j5 bzImagesudo make -j5 modules

-JN can open n threads make. N = 3-5

sudo make modules_install 

(This step will overwrite existing modules/lib/modules, and some drivers may have problems)

Then copy the. config, system. Map and arch/x86/boot/bzimage under the/usr/src/linux-3.1.0 to/boot and rename it the config-3.1.0 system. Map-3.1.0 vmlinuz-3.1.0.

sudo cp -a .config /boot/config-3.1.0sudo cp -a System.map /boot/System.map-3.1.0sudo cp arch/x86/boot/bzImage /boot/vmlinuz-3.1.0

Create initrd

Sudo Update-initramfs-C-v-K 3.1.0 // create a new initramfs startup, generating initrd. img-3.1.0

Update grub

sudo grub-mkconfig

After the check is complete, write the configuration file to grub. cfg.

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

3. Install the NVIDIA official graphics card driver

Download the NVIDIA-Linux-x86-285.05.09.run installation file on the official website. (It is strongly recommended that you download the installation instructions and save them as TXT files to facilitate viewing on the console interface.) restart and enter the newly compiled Ubuntu GNU/Linux, with Linux 3.1.0 and xen 4.1.2 startup options, start a new kernel. No video card driver. Run sudo Sh./NVIDIA-Linux-x86-285.05.09.run, follow the prompts all the way to yes can be successfully installed. (If you're lucky enough to restart, you can enter the graphic interface. However, there is another problem: the window title will disappear and the problem persists: Modify the/etc/X11/Xorg. conf file (back up first ),
