原文地址:Xen 4.0.1 on ubuntu 10.04 作者:cywcdwxjf

The most recent pvops kernel allows to enable kernel modesetting (KMS) under Xen 4.0.1-rc6 on top of Ubuntu Lucid Server and Fedora 13. Actually , current setup of Xen 4.0.1&PVOPS on top of Ubuntu 10.04 Server is different from

: How to install Xen 4.0 ([1])

and brief instructions follow bellow. Status of the problem in general along with list of video adapters been tested may be viewed at

([3]) .

Current test has been done with Radeon HD 4650, which is not on list above.
Install packages bellow :-

apt-get install libcurl4-openssl-dev \
xserver-xorg-dev \
mercurial gitk \
build-essential \
libncurses5-dev \
uuid-dev gawk \
gettext texinfo bcc \
libncurses5-dev dpkg-dev debhelper \
iasl texinfo bridge-utils bison flex \
kernel-package fakeroot

apt-get build-dep xen-3.3

Setup pvops kernel with KMS enabled.
Now clone Jeremy Fitzhardinge git repository and checkout branch xen/stable-2.6.32.x

cd /usr/src
git clone
git:// linux-2.6-xen
cd linux-2.6-xen
git checkout -b xen/stable-2.6.32.x origin/xen/stable-2.6.32.x
make menuconfig # and setup Xen Dom0 support

Build kernel in Debian way. Config

export CONCURRENCY_LEVEL=(number_of_cores) +1
make-kpkg clean
fakeroot make-kpkg --initrd --append-to-version=-xen kernel-image kernel-headers
dpkg -i ../linux-image-
update-initramfs -c -k

Set up Xen 4.0.1-rc6

# cd /usr/src
# hg clone
# cd xen-4.0-testing.hg
# make xen
# make tools
# make install-xen
# make install-tools PYTHON_PREFIX_ARG=

Set up xend,xendomains to run as services

update-rc.d xend defaults 20 21
update-rc.d xendomains defaults 21 20

Reboot in Xen with grub entry

menuentry "Xen 4.0.1-rc6 / Ubuntu 10.04 kernel" {
insmod ext2
set root='(hd0,9)'
multiboot (hd0,9)/boot/xen.gz dummy=dummy
module (hd0,9)/boot/vmlinuz- dummy=dummy root=/dev/sdb5 ro console=tty0
module (hd1,5)/boot/initrd.img-
