The commit that seems to be causing the problem on OSX is this one:

commit 2ed6cc7bec41dd344d41ea1531f6760c93099128
Author: Daniel P. Berrange <berrange redhat com>
Date:   Wed Mar 2 16:59:54 2011 +0000

    Expose event loop implementation as a public API
    
    Not all applications have an existing event loop they need
    to integrate with. Forcing them to implement the libvirt
    event loop integration APIs is an undue burden. This just
    exposes our simple poll() based implementation for apps
    to use. So instead of calling
    
       virEventRegister(....callbacks...)
    
    The app would call
    
       virEventRegisterDefaultImpl()
    
    And then have a thread somewhere calling
    
        static bool quit = false;
        ....
        while (!quit)
          virEventRunDefaultImpl()
    
    * daemon/libvirtd.c, tools/console.c,
      tools/virsh.c: Convert to public event loop APIs
    * include/libvirt/libvirt.h.in, src/libvirt_private.syms: Add
      virEventRegisterDefaultImpl and virEventRunDefaultImpl
    * src/util/event.c: Implement virEventRegisterDefaultImpl
      and virEventRunDefaultImpl using poll() event loop
    * src/util/event_poll.c: Add full error reporting
    * src/util/virterror.c, include/libvirt/virterror.h: Add
      VIR_FROM_EVENTS


Moving to the commit right before it, and virsh works starts
up fine.  With the above commit though, virsh just hangs on OSX.

The options compiled in for the above testing were:

  Compiled with support for:
   Hypervisors: OpenVZ VirtualBox ESX Test
   Networking: Remote
   Storage:
   Miscellaneous: Debug Readline

Anyone have ideas for a workaround or other useful things to
test?

Regards and best wishes,
