after dump, instead of sending ACPI reboot event.

 Dumps the core of a domain to a file for analysis.
 If I<--live> is specified, the domain continues to run until the core
 dump is complete, rather than pausing up front.
 If I<--crash> is specified, the domain is halted with a crashed status,
 rather than merely left in a paused state.
+If I<--reset> is specified, the domain is reset after successful dump.
+Note, these three switches are mutually exclusive.
 If I<--bypass-cache> is specified, the save will avoid the file system
 cache, although this may slow down the operation.
