Note: During one of the sets for the daily quest, the third daily quest hub for Golden Lotus (only able to be seen at honored+ rep), these stonebark tricksters seem to be replaced with mogu's to kill for the daily quests for the Golden Lotus. This can be irritating when farming them for sky shards and motes, but it doesn't happen too often.
The name of the virtual server is always the same as the name of the SQL Network Name (the SQL Virtual Server Network Name). You can change the name of the virtual server, you cannot change the instance name like in the case of standalone named instance. You can change a virtual SQL server named SQLServerinstance1 to some other name, such as SQLServerNewinstance1, but the instance part of the name, instance1, will remain unchanged.
An instance is either the default, unnamed instance, or it is a named instance. When SQL Server 2005 is in installed in the default instance, it does not require a client to specify the name of the instance to make a connection. The client only has to know the server name.
