Xen Virtualization on Linux and Solaris

This post follows up Mark McLoughlin’s ANNOUNCE: Rawhide virt repo for F11 users:- Another update available in http://markmc.fedorapeople.org/virt-preview
It’s targeting install the most recent version of Fedora’s libvirt on F11 and testing virt-manager and virt-install to work properly with Xen 3.4.1 Hypervisor been installed on F11 via xen 3.4.1-1 src.rpm downloaded from http://kojipkgs.fedoraproject.org/packages/xen/3.4.1/1.fc12/
PVOPS kernel 2.6.31-rc6 has been installed via Jeremy Fitzhardinge Git Repository to support Xen 3.4.1 Dom0.

Install packages required by rpmbuild:-

# yum install transfig texi2html libaio-devel dev86 glibc-devel.i586

Download xen-3.4.1-1.fc12.src.rpm

# wget http://kojipkgs.fedoraproject.org/packages/xen/3.4.1/1.fc12/src/xen-3.4.1-1.fc12.src.rpm
# rpm -iv xen-3.4.1-1.fc12.src.rpm
# cd /root/rpmbuild/SPECS
# rpmbuild -ba ./xen.spec

To install hypervisor and tools

# cd ../RPMS/x86_64
# yum install xen-3.4.1-1.fc11.x86_64.rpm \
