[Qemu-devel] [PATCH] vl.c: fix regression when reading machine type from config file

[Marcel Apfelbaum <marcel@redhat.com>]

After 'Machine as QOM' series the machine type input triggers
the creation of the machine class.
If the machine type is set in the configuration file, the machine
class is not updated accordingly and remains the default.

Fixed that by querying the machine options after the configuration
file is loaded.
