Xen Virtualization on Linux and Solaris

Xen 3.3.1 port to Ubuntu Intrepid Server via Novell's Xen-ified kernel 2.6.27.5

The root cause of port mentioned above to run 64-bit Solaris 10U6 HVM on SMP box with
several vcpus. Install openssl,x11,gettext,python-devel packages required by Xen and bcc&libc6-dev-i386 via Synaptic Manager.The last two packages are needed to compile "hvmloader" and related utilities


# cd /usr/src
# tar zxvf xen-3.3.1.tar.gz
# cd xen-3.3.1
# make xen
# make install-xen
# make tools
# make install-tools

Compile "hvmloader"


# cd tools/firmware
# make
# make install

Install Novell's Kernel per [1]:-


# apt-get install build-essential libncurses5-dev gawk mercurial
# mkdir -p /home/boris/build/linux-2.6.27-xen
# cd /usr/src/
# hg clone http://xenbits.xensource.com/ext/linux-2.6.27-xen.hg
# cd linux-2.6.27-xen.hg
# make O=/home/boris/build/linux-2.6.27-xen/ \
menuconfig
# make O=/home/boris/build/linux-2.6.27-xen/ -j12
# make O=/home/boris/build/linux-2.6.27-xen/ \
modules_install install
# depmod 2.6.27.5
# mkinitramfs -o /boot/initrd-2.6.27.5.img 2.6.27.5

Setup /etc/init.d/xend and xendomains to automatic startaup
Rebooted the system with grub’s entry:-


title Xen 3.3 / Ubuntu 8.10, kernel 2.6.27-xen
kernel /boot/xen-3.3.1.gz
module /boot/vmlinuz-2.6.27.5 root=/dev/sdb1 ro console=tty0
module /boot/initrd-2.6.27.5.img
