**[2]Install Xen Dom0-capable linux kernel**
—————————————–

Linux 3 fully supports Xen Virtualisation but it is not available for Fedora 15, so I use linux 3 which built for Fedora 16 (download  from  http://koji.fedoraproject.org/).

Note that since I mixed with Fedora 16 packages, this will make my current Fedora 15 unstable

[root@localhost xen-kernel]# yum install kernel-3.0-0.rc5.git0.1.fc16.x86_64.rpm mdadm-3.2.2-1.fc16.x86_64.rpm

———————————————————————————-
**[3 ]Use grubby to create a grub.conf entry in a manner such as the following:
———————————————————————————-
[root@localhost xen-kernel]# KERNEL_VERSION=3.0-0.rc5.git0.1.fc16.x86_64
[root@localhost xen-kernel]# ROOT_UUID=`blkid /dev/sda1 -s UUID | awk -F = ‘{ print $2 }’ | tr -d ‘”‘`

//NOTE THAT –args=”…” argument below should be similar to your current fedora installation grub.conf entry
[root@localhost xen-kernel]# grubby \
–add-multiboot=/boot/xen.gz \
–add-kernel=/boot/vmlinuz-${KERNEL_VERSION} \
–args=”ro root=/dev/mapper/VolGroup-LogVolRoot rd_LVM_LV=VolGroup/LogVolRoot rd_LUKS_UUID=luks-f22f5b85-ac46-4b3b-944b-42d4733c3771 rd_LVM_LV=VolGroup/LogVolSwap rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=us” \
–initrd=/boot/initramfs-${KERNEL_VERSION}.img \
–title=”Fedora (${KERNEL_VERSION})”

————————————————————–
**[4]Reboot and select your Xen kernel in the GRUB boot menu
————————————————————–

————————————————————————————————————
**[5]Install Virtual Machine Manager (virt-manager) for adminisrating virtual machines for Xen, KVM and QEmu
————————————————————————————————————
[root@localhost ~]# yum install virt-manager libvirt virt-viewer
