These days I want to install a new Linux kernel in Guest Operating System.
The original version of Guest OS is 2.6.32, but I need a kernel version 3.10.
I have tried several ways and following steps is just one of methods which can
work:
1. We should download a linux kernel (3.10.56) from kernel.org, after downloading
linux-3.10.56.tar.xz, using command tar -xf linux-3.10.56.tar.xz can get resource
code directory.
2. The key point is to modify the .config file, of course, we can change this file
using command make menuconfig. We should first enter the menu Processor type
and features, then enter the menu Linux Guest Support, and the last step is to
enable all the options belonging this menu.
3. After exiting this menuconfig and saving the changes, we should using the follwoing
commands to recompile and install the new kernel.
make -j 4 (4 is number of cores in this computer)
make modules
make modules_install
make install
4. Then reboot the computer and select the new kernel to load.
