Re: [libvirt] [PATCH 3/3] virsh: Unregister the connection close notifier upon termination

Before closing the connection we unregister the close callback

virsh connect!). Further, the messages on virConnectClose != 0

In that case the callback should be registered also on "virsh connect" and also you did not unregister the callback there if you are changing from an active connection.

are a bit more specific now.

I like this change.

When you actually register and unregister the callback in cmdConnect, you don't need to have this global variable. This change will need rearrangement of some code. I'll send the patch for this.
