q35: Improve sample configuration files
Instead of having a single sample configuration file, we now have several: * q35-emulated.cfg documents the default devices QEMU adds to a q35 guest and the additional devices that are pretty much guaranteed to be present in a physical q35-based machine; * q35-virtio-graphical.cfg can be used to start a fully-featured (USB, graphical console, audio, etc.) guest that uses VirtIO instead of emulated devices; * q35-virtio-serial.cfg is similar but has a minimal set of devices and uses the serial console. All configuration files are fully commented and neatly organized.

-# qemu -M q35 creates a bare machine with just the very essential

-#
-# 00.0 - Host bridge
-# 1f.0 - ISA bridge / LPC
-# 1f.2 - SATA (AHCI) controller
-# 1f.3 - SMBus controller
-#
-# This config file documents the other devices and how they are

-#
-# 19.0 - Ethernet controller (not created, our e1000 emulation
-# doesn't emulate the ich9 device).
-# 1a.* - USB Controller #2 (ehci + uhci companions)
-# 1b.0 - HD Audio Controller
-# 1c.* - PCI Express Ports
-# 1d.* - USB Controller #1 (ehci + uhci companions,
-# "qemu -M q35 -usb" creates these too)
-# 1e.0 - PCI Bridge

+# 00:00.0 Host bridge
+# 00:1f.0 ISA bridge / LPC
+# 00:1f.2 SATA (AHCI) controller
+# 00:1f.3 SMBus controller
+#
+# This configuration file adds a number of other useful
+# devices, more specifically:
+#
+# 00.1c.* PCI bridge (PCI Express Root Ports)
+# 01:00.0 SCSI storage controller
+# 02:00.0 Ethernet controller
+#
+# More information about these devices is available below.
+#
+# We use '-display none' to prevent QEMU from creating a
+# graphical display window, which would serve no use in
+# this specific configuration, and '-serial mon:stdio' to
+# multiplex the guest's serial console and the QEMU monitor
+# to the host's stdio; use 'Ctrl+A h' to learn how to
+# switch between the two and more.
+
+
+# Machine options
+# =========================================================
+#
+# We use the q35 machine type and enable KVM acceleration
+# for better performance.
+#
+# Using less than 1 GiB of memory is probably not going to
+# yield good performance in the guest, and might even lead
+# to obscure boot issues in some cases.
