I've attached the logs you requested, plus 4 xen config files in case 
the problem lies there.

I get no messages in /var/log/xend/xend.log when trying to use virt-
manager (not on app startup, not when error occurs, not on app 
shutdown).  But there are a whole lot of warnings about failed API calls 
during initial xend startup.

Since my first message, I have yum-updated my machine and now get a 
warning when starting virt-manager on the command line.  This warning 
seems unrelated to the connection problem, however:
-------------------->8------------------
***MEMORY-WARNING***: virt-manager.py[4554]: GSlice: g_thread_init() 
must be called before all other GLib functions; memory corruption due to 
late invocation of g_thread_init() has been detected; this program is 
likely to crash, leak or unexpectedly abort soon...
--------------------8<------------------

Here is my configuration:
Fedora 7   (fully updated)
Xen 3.1    (installed from XenSource tarball using vanilla kernel)
python-virtinst-0.103.0-3.fc7 (installed from Fedora 7 rpm)
libvirt-0.2.3-1.fc8           (installed from Fedora 7 rpm)
libvirt-python-0.2.3-1.fc8    (installed from Fedora 7 rpm)
virt-manager-0.4.0-2.fc7      (installed from Fedora 7 rpm)

I had to install Xen from source because the Fedora 7 rpms didn't work 
on my hardware: dom0 wouldn't boot.  This isn't the usual misconfigured 
grub or missing initrd or anything...this is an early hardware detection 
error.  I've been dealing with such errors for a while: Linux doesn't 
always play nicely with the new Intel 965 boards and also gets confused 
by sata optical drives.

It occurs to me that xend used to have 2 different connection options.  
Does it still?  Do I need to change a setting in one of the xend, xm, or 
xenapi config files?

Thanks,
