How you install from source? xm should be located in /usr/sbin/xm so
is /usr/sbin in your PATH?  Are you using root or normal user?

Did you compile with XEN_PYTHON_NATIVE_INSTALL=1 option?  If I
remember it correctly, default is installed in
/usr/lib/python/site-package/xen for x86_32 so I assume for x86_64
should be in /usr/lib64/python/site-package/xen unless
XEN_PYTHON_NATIVE_INSTALL is set during compilation.  Someone correct
me if I am wrong though :p  If you compile from source did you also
install vendor xen package as well?  I hope not... ...

Kindest regards,
Giam Teck Choon

P.S. Sorry, should reply to xen-devel list instead of replying to the
sender directly.
