# mach-virt - VirtIO guest (serial console)
|
|
# =========================================================
|
|
#
|
|
# Usage:
|
|
#
|
|
# $ qemu-system-aarch64 \
|
|
# -nodefaults \
|
|
# -readconfig mach-virt-serial.cfg \
|
|
# -display none -serial mon:stdio \
|
|
# -cpu host
|
|
#
|
|
# You will probably need to tweak the lines marked as
|
|
# CHANGE ME before being able to use this configuration!
|
|
#
|
|
# The guest will have a selection of VirtIO devices
|
|
# tailored towards optimal performance with modern guests,
|
|
# and will be accessed through the serial console.
|
|
#
|
|
# ---------------------------------------------------------
|
|
#
|
|
# Using -nodefaults is required to have full control over
|
|
# the virtual hardware: when it's specified, QEMU will
|
|
# populate the board with only the builtin peripherals,
|
|
# such as the PL011 UART, plus a PCI Express Root Bus; the
|
|
# user will then have to explicitly add further devices.
|
|
#
|
|
# The PCI Express Root Bus shows up in the guest as:
|
|
#
|
|
# 00:00.0 Host bridge
|
|
#
|
|
# 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 virt 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.
|
|
#
|
|
# Unfortunately, there is no way to configure the CPU model
|
|
# in this file, so it will have to be provided on the
|
|
# command line, but we can configure the guest to use the
|
|
# same GIC version as the host.

# Firmware configuration
|
|
# =========================================================
|
|
#
|
|
# There are two parts to the firmware: a read-only image
|
|
# containing the executable code, which is shared between
|
|
# guests, and a read/write variable store that is owned
|
|
# by one specific guest, exclusively, and is used to
|
|
# record information such as the UEFI boot order.
|
|
#
|
|
# For any new guest, its permanent, private variable store
|
|
# should initially be copied from the template file
|
|
# provided along with the firmware binary.
|
|
#
|
|
# Depending on the OS distribution you're using on the
|
|
# host, the name of the package containing the firmware
|
|
# binary and variable store template, as well as the paths
|
|
# to the files themselves, will be different. For example:
|
|
#
|
|
# Fedora
|
|
# edk2-aarch64 (pkg)
|
|
# /usr/share/edk2/aarch64/QEMU_EFI-pflash.raw (bin)
|
|
# /usr/share/edk2/aarch64/vars-template-pflash.raw (var)
|
|
#
|
|
# RHEL
|
|
# AAVMF (pkg)
