sudo yum install xen
Xen installed without errors and I rebooted. In the Grub2 list I selected Xen 4.1.2 and then selected the option:
Fedora Linux, with Xen 4.1.2 and Linux 3.3.0-4.fc16.x86_64
The boot process starts (i notice that loading ramdisk is very short) and then shortly thereafter the boot fails and the system reboots without any error.
I tried checking the boot log but I'm not sure I'm looking at the right log.
The only problem I see in the boot is
Started SYSV: sandbox, xguest and other apps that want to use pam_names$
Failed to start Xenstored - daemon managing xenstore file system
