Yup, that's it, thanks.  I began to suspect it was something like this,
but couldn't find any documentation about virt-manager's needs for 
connecting to xend.  Is the XenSource tarball's default out of date and 
should they use the unix server by default?  Or is this interface used 
only by some apps like virt-manager?

Also, I don't know if you're worried about the secondary warning I got:

***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...

Thanks again,
