Re: [libvirt] PATCH: Improve python exception messages

Most of the libvirt python API bindings use code snippet like this when raising an exception: if ret is None:raise libvirtError('virConnectOpen() failed') THis sets the message associated with the exception to "virConnectOpen() failed" This contains essentially zero useful information - you can see that it was virConnectOpen which failed from the stack trace. Now the libvirt error object has a real message, such as "authentication failed" Or "unable to connect to '/var/run/libvirt/libvirt-sock': Connection refused" This patch makes sure we extract this real error message and use it to set the message associated with the exception object. This is one step in getting better error reporting for virt-install/virt-manager, which is particularly needed for remote connections
