【安裝 Xen 4.0 最新測試版】

[Step1：編譯與安裝 Xen Paravirt_Ops Linux kernel - 2.6.32.16]

$ cd /usr/src
$ sudo git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-xen
$ cd ./linux-2.6-xen
$ sudo git reset --hard
$ sudo git checkout -b xen/stable-2.6.32.x origin/xen/stable-2.6.32.x
$ sudo git pull   //往後在此更新至 latest kernel revision//
$ sudo make menuconfig   //See the attached kernel config file for details//
$ sudo make -j 4
$ sudo make modules -j 4
$ sudo make modules_install install
$ sudo depmod -a
$ sudo mkinitramfs -o /boot/initrd.img-2.6.32.16 2.6.32.16

• 修改 Grub.cfg 開機選單 (Grub2路徑:/boot/grub/grub.cfg)

   menuentry 'Xen-4.x, with Linux 2.6.32.16' --class ubuntu --class gnu-linux --class gnu --class os {
            recordfail
            insmod ext2
            set root='(hd0,1)'
            multiboot (hd0,1)/boot/xen-4.0.gz dummy=dummy
            module  /boot/vmlinuz-2.6.32.16 dummy=dummy root=UUID=04c43ab3-b033-448d-aef9-c75beb222f99 ro nomodeset
            module  /boot/initrd.img-2.6.32.16
  }
  

[Step2：編譯與安裝 Xen-4.x Hypersior Testing/Stable版本]

### (1) Testing ###
$ cd /usr/src
$ sudo hg clone http://xenbits.xen.org/xen-4.0-testing.hg
$ cd ./xen-4.0-testing.hg
### (2) Stable ###
$ wget http://bits.xensource.com/oss-xen/release/4.0.1/xen-4.0.1.tar.gz
$ sudo tar zxvf xen-4.0.1.tar.gz -C /usr/src/ 
$ cd /usr/src/xen-4.0.1
##################
$ sudo make xen -j 4
$ sudo make tools -j 4
$ sudo make stubdom -j 4
$ sudo make install-xen
$ sudo make install-tools PYTHON_PREFIX_ARG=
$ sudo make install-stubdom
$ sudo update-rc.d xend defaults 20 21
$ sudo update-rc.d xendomains defaults 21 20
$ sudo reboot

[Additional Step：Up-to-date Xen-4.x Hypersior]

$ cd xen-4.0-testing.hg
$ make clean
$ hg pull
$ hg update
