| 2 | # ========================================================= |
| 3 | # |
| 4 | # Usage: |
| 5 | # |
| 6 | # $ qemu-system-x86_64 \ |
| 7 | # -nodefaults \ |
| 8 | # -readconfig q35-emulated.cfg |
| 9 | # |
| 10 | # You will probably need to tweak the lines marked as |
| 11 | # CHANGE ME before being able to use this configuration! |
| 12 | # |
| 13 | # The guest will have a selection of emulated devices that |
| 14 | # closely resembles that of a physical machine, and will be |
| 15 | # accessed through a graphical console. |
| 16 | # |
| 17 | # --------------------------------------------------------- |
| 18 | # |
| 19 | # Using -nodefaults is required to have full control over |
| 20 | # the virtual hardware: when it's specified, QEMU will |
| 21 | # populate the board with only the builtin peripherals |
| 22 | # plus a small selection of core PCI devices and |
| 23 | # controllers; the user will then have to explicitly add |
| 24 | # further devices. |
| 25 | # |
| 26 | # The core PCI devices show up in the guest as: |
| 27 | # |
| 28 | # 00:00.0 Host bridge |
| 29 | # 00:1f.0 ISA bridge / LPC |
| 30 | # 00:1f.2 SATA (AHCI) controller |
| 31 | # 00:1f.3 SMBus controller |
| 32 | # |
| 33 | # This configuration file adds a number of devices that |
| 34 | # are pretty much guaranteed to be present in every single |
| 35 | # physical machine based on q35, more specifically: |
| 36 | # |
| 37 | # 00:01.0 VGA compatible controller |
| 38 | # 00:19.0 Ethernet controller |
| 39 | # 00:1a.* USB controller (#2) |
| 40 | # 00:1b.0 Audio device |
| 41 | # 00:1c.* PCI bridge (PCI Express Root Ports) |
| 42 | # 00:1d.* USB Controller (#1) |
| 43 | # 00:1e.0 PCI bridge (legacy PCI bridge) |
| 44 | # |
| 45 | # More information about these devices is available below. |

| 52 | # for better performance. |

| 54 | # Using less than 1 GiB of memory is probably not going to |
| 55 | # yield good performance in the guest, and might even lead |
| 56 | # to obscure boot issues in some cases. |
| 57 | # |
| 58 | # Unfortunately, there is no way to configure the CPU model |
| 59 | # in this file, so it will have to be provided on the |
