Just starting a Linux HVM guest and executing lspci in the guest is a
good start :)
The entry to point to start all the emulated devices in qemu is
pc_init1 in hw/pc.c, from there you can find out all the
initialization functions of the emulated hardware provided by qemu to
the guest.
The main ones are the graphic card (two models available:
hw/cirrus_vga.c and hw/vga.c), network cards (two models available:
hw/e1000.c, hw/rtl8139.c), PIIX4 (hw/piix4acpi.c), PIIX3 (hw/piix_pci.c,
hw/ide.c, hw/usb-uhci.c), usb devices (hw/usb-hid.c), the xen pci
platofirm device (hw/xen_platform.c) and the serial card (hw/serial.c).
