Here you entered root

but here it asks for intel123's, that's unexpected. Did you edit this
one before mailing it, or is there really this mismatch?

Outputting (null) here is actually a bug. The only way this can happen
is when the login attempt fails but the XenServer doesn't provide an
error message. Maybe have a look at the XenServer logs to see if it
says something about a failed login attempt.

The XenAPI driver expects a server name. xenapi:/// _could_ be treated
as xenapi://localhost, but it's not implemented that way.

Running 'make rpm' should build an libvirt-devel RPM package for you.
