# Virtual Machine environment requirements:
# 8 GiB of RAM (for DPDK)
# enable intel_kvm on your host machine

# The purpose of this script is to provide a simple procedure for spinning up a new
# virtual test environment capable of running our whole test suite. This script, when
# applied to a fresh install of fedora 26 server will install all of the necessary dependencies
# to run almost the complete test suite. The main exception being VHost. Vhost requires the
# configuration of a second virtual machine. instructions for how to configure
# that vm are included in the file TEST_ENV_SETUP_README inside this repository

# it is important to enable nesting for vms in kernel command line of your machine for the vhost tests.
#     in /etc/default/grub
#     append the following to the GRUB_CMDLINE_LINUX line
#     intel_iommu=on kvm-intel.nested=1

# We have made a lot of progress with removing hardcoded paths from the tests,
# but it may be easiest if you create your user with the name sys_sgsw for now.
