Xen Virtualization on Linux and Solaris

Recent pulling GRUB2 supporting CSs into xen-3.4-testing.hg immediately makes sense to build xen 3.4.3-2.fc12.src.rpm to be able to set up current version of 3.4.3 Xen Hypervisor on Fedora 12 working pretty smoothly with Libvirt packages ( vs Xen 4.0) and the at same time supporting GRUB2 PV DomUs , say Ubuntu 9.10 Server or Debian Squeeze. Download xen-3.4.2-2.fc13.src.rpm

# rpm -iv xen-3.4.2-2.fc13.src.rpm
# hg clone http://xenbits.xensource.com/xen-3.4-testing.hg
# cp -R xen-3.4-testing.hg xen-3.4.3
# cd xen-3.4.3
# git clone git://xenbits.xensource.com/qemu-xen-3.4-testing.git qemu-xen.git
# cp qemu-xen.git.tar.gz /root/rpmbuild/SOURCES/qemu-xen.git.xen-3.4.3-rc3.tar.gz
# cd ..
# cp xen-3.4.3.tar.gz /root/rpmbuild/SOURCES/xen-3.4.3.tar.gz

Place also localqemu-xen.patch into SOURCES :

Now cd ../SPECS and modify xen.spec as follows :

Now install current Xen 3.4.3 Hypervisor on Fedora12 and proceed as usual.

yum install xen-3.4.3-2.fc12.x86_64.rpm \

Install Libvirt

# yum install libvirt libvirt-python python-virtinst \

PVOPS kernel 2.6.32.9 has been installed via Jeremy Fitzhardinge
Git Repository to support Xen 3.4.3 Dom0.

# git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-xen
# cd linux-2.6-xen
# git checkout origin/xen/stable -b xen/stable

Now we have built environment allows install OSOL133 via virsh ( been built against Libvirt 0.1.7) and the time have Ubuntu Karmic Koala HVM and PV DomUs installed at Xen 3.4.3 Dom0 and sharing the same image device. View :-
Set up OSOL PV Guests (build<=131) via virsh on Xen 3.4.3 Dom0 on top of Ubuntu 9.10 Server
Set up Ubuntu Karmic Server (Grub2) PV Guest at Xen 4.0-rc4 (2.6.32 pvops) on top of Fedora12
