Vagrant-libvirt QEMU customization

Vagrant libvirt allows the user to customize the virtual machines to add features and use QEMU options that are not exposed via the plugin itself. For this it uses the libvirt's custom QEMU arguments options which appends the args at the very end of the command line. This allows you to not only add new arguments, it allows you to also override the plugin constructed defaults.

In the snippet below the

machine and memory default plugin arguments are over-ridden
an additional NVDIMM device is created and added to the machine

Create the directory structure:

touch docker-compose.yml
mkdir -p volumes/{config,file,logs}

Populate the vault config vault.json:

Docker compose as a systemd unit

Create file /etc/systemd/system/[email protected]. SystemD calling binaries using an absolute path. In my case is prefixed by /usr/local/bin, you should use paths specific for your environment.

Tuning Intel Skylake and beyond for optimal performance and feature level support on Linux:

Note that on Skylake, Kabylake (and the now cancelled "Broxton") SKUs, functionality such as power saving, GPU scheduling and HDMI audio have been moved onto binary-only firmware, and as such, the GuC and the HuC blobs must be loaded at run-time to access this functionality.

Enabling GuC and HuC on Skylake and above requires a few extra parameters be passed to the kernel before boot.

Instructions provided for both Fedora and Ubuntu (including Debian):

Note that the firmware for these GPUs is often packaged by your distributor, and as such, you can confirm the firmware blob's availability by running:

Quickly check for supported NVENC and NPP hardware acceleration capabilities in FFmpeg on your platform:

Depending on how you built ffmpeg, you may want to check the supported NVENC-based hardware acceleration capabilities in ffmpeg by running:

$ for i in encoders decoders filters; do
    echo $i:; ffmpeg -hide_banner -${i} | egrep -i "npp|cuvid|nvenc|cuda|nvdec"
done

Sample output (as on my testbed):
