Thanks a lot for the reply. I checked the setting in my config file and they look correct as specified by the webpage. I am able to connect to the unix socket but my login to xend is failing.

What I am looking for is the exact function call that is made by libvirt to connect to xen daemon. i.e. the function that makes libvirt send out xml RPC message for xend to read.

session.login_with_password() is not supported by xenAPI version being used in Red Hat. Please help me with the substitute of this method in Red Hat.

Thanks
Vaibhav

Libvirt talks to XenD using its UNIX socket, and SEXPR interface. This
page gives a quick list of config settings you need in XenD to make it
work with libvirt:
