Summary:

1) xentrace -e all trace.out (this command will record all the events)

2) cat trace.out| xentrace_format formats | more

xentrace_format is a program to translate the binary format of trace.out to text format.

The formats file is in /tools/xentrace/formats.   In the same directory, there is a file called xentrace_format. It is not the "format" file, it is a python program. If you use it as format file, you will get an error "SyntaxError: Unexpected EOF while parsing".

Compiling chapter 2 example from "The Definitive Guide to the Xen" book

When compiling on a PAE enabled Xen hypvervisor, you will get follwing error:

"guest type xen-3.0-x86_32 not supported by xen kernel"

Solution: modify the bootstrap.x86_32.S file, change "PAE=no" to "PAE=yes".

Fedora 9 and 10 does not support running as Dom 0

Since Fedora 9, they will only support to run as Dom U.

Clone Xen VM

The best way for now is to use virt-clone. It supports automate cloning and support other virtualization technolgoies such as QEMU.
Here is the man page:
