Summary of ubuntu 14.04 compilation and installation of xen4.4

1. installation environment

Operating System: ubuntu14.04

Xen version: xen4.4

2. Install dependency packages

Install the dependency package before installing xen. After constantly trying, summarize the following dependency packages to be installed.

Suso apt-Get install GCC make binutils zlib1g-dev Python-Dev

Sudo apt-Get install libncurses5-dev libcurl4-openssl-dev libx11-dev

Sudo apt-Get install UUID-dev libyajl-dev libaio-dev libglib2.0-dev libpixman-1-dev

Sudo apt-Get install PKG-config bridge-utils iproute udev bison flex gettext

Sudo apt-Get install bin86 bcc iasl ocaml-NOx ocaml-findlib cmake markdown figlet git libc6-dev-i386

Sudo apt-Get install texinfo texlive-latex-base texlive-latex-recommended texlive-fonts-extra

Sudo apt-Get install texlive-fonts-recommended pciutils-dev mercurial

The above dependency packages are mainly used to successfully compile and install xen4.4.

3. xen Source File Download

Xen4.4 source file address http://www.xenproject.org/downloads-list/xen-archives/xen-44-series/xen-440.html

The source file is downloaded as a tar package, which can be first downloaded to Windows and then copied to the virtual machine using winscp, or directly downloaded from the virtual machine.

Note: The Tar package must be decompressed in Ubuntu. If it is decompressed in windows and then copied to Ubuntu, the file execution level will be changed, compilation errors may occur.

4. xen source file Compilation

Decompress the source file to a directory, CD it to the directory where the source file is located, and perform the steps according to the steps described in readme in the source file.

#./Configure
# Make World
# Make install

However, after executing make world, an error is displayed as follows:

Tpmback. C: In function 'tpmif _ change_state ':
Tpmback. c: 350: 4: Error: Format '% d' expects argument of Type 'int *', but argument 3 has type 'enum xenbus_state * '[-werror = format =]
If (sscanf (value, "% d", & readst )! = 1 ){

After this error occurs, the compilation of the source file cannot be executed. After finding the relevant information, we will find a discussion:

Address of the discussion: http://thread.gmane.org/gmane.comp.emulators.xen.devel/207530/focus=207948

The result of the discussion seems to be a bug and a patch is required.

Ian checked it. It should be a member of the hypervisor project team.

5. Summary

So far, the installation block of xen4.4 has been installed, and the installation method in Ubuntu should be available, and the test will continue later.
