From 9fc1babd959abeb01001a5a507c515c34209fe84 Mon Sep 17 00:00:00 2001 From: Mark McLoughlin Date: Wed, 22 Jul 2009 10:02:50 +0100 Subject: [PATCH] Add machine type aliases Add an 'alias' field to QEMUMachine and display it in the output of 'qemu -M ?' with an '(aliased to foo)' suffix. Aliases can change targets in newer versions of qemu, so management tools may choose canonicalize machine types to ensure that if a user chooses an alias, that the actual machine type used will remain compatible in future. This is intended to mimic a symlink to a machine description file.
