NAME
       Sys::Virt::Error - error object for libvirt APIs

DESCRIPTION
       The "Sys::Virt::Error" class provides an encoding of the libvirt errors. Instances of this
       object can be thrown by pretty much any of the Sys::Virt APIs.

METHODS
       $err->stringify
	   Convert the object into string format suitable for printing on a console to inform a
	   user of the error.

       my $code = $err->level
	   Return the raw error level represented by this error. One of the ERROR LEVEL CONSTANTS

       my $code = $err->code
	   Return the raw error code represented by this error. One of the ERROR CODE CONSTANTS

       my $from = $err->domain
	   Return the error domain raising this error. One of the ERROR DOMAIN CONSTANTS

       my $msg = $err->message
	   Return an informative message describing the error condition.
