Helper and debugging scripts for the Virtio-forwarder are located in
/usr/lib[64]/virtio-forwarder/.
Here are pointers to using some of the more useful one, from the docs:
- virtioforwarder_stats.py: Gathers statistics (including rate stats) from running relay instances.
- virtioforwarder_core_pinner.py: Manually pin relay instances to CPUs at runtime. Uses the same syntax asmthe environment file, that is, -virtio-cpu=RN:Ci,Cj. Run without arguments to get the current relay to CPUmapping. Note that the mappings may be overridden by the load balancer if it is also running. The same is true for mappings provided in the configuration file.
- virtioforwarder_monitor_load.py: Provides a bar-like representation of the current load on worker CPUs. Useful to monitor the work of the load balancer.
System logs can be viewed by running
journalctl -u virtio-forwarder -u vio4wd_core_scheduler on
systemd-enabled systems.
Syslog provides the same information on older systems.
Hope this helps....

modules-load.d
MODULES-LOAD.D(5) modules-load.d MODULES-LOAD.D(5)
NAME
modules-load.d - Configure kernel modules to load at boot
SYNOPSIS
/etc/modules-load.d/*.conf
/run/modules-load.d/*.conf
/usr/lib/modules-load.d/*.conf
DESCRIPTION
systemd-modules-load.service(8) reads files from the above directories which contain kernel modules to load during boot in a static list.
Each configuration file is named in the style of /etc/modules-load.d/program.conf. Note that it is usually a better idea to rely on the
automatic module loading by PCI IDs, USB IDs, DMI IDs or similar triggers encoded in the kernel modules themselves instead of static
configuration like this. In fact, most modern kernel modules are prepared for automatic loading already.
CONFIGURATION FORMAT
The configuration files should simply contain a list of kernel module names to load, separated by newlines. Empty lines and lines whose
first non-whitespace character is # or ; are ignored.
CONFIGURATION DIRECTORIES AND PRECEDENCE
Configuration files are read from directories in /etc/, /run/, and /lib/, in order of precedence. Each configuration file in these
configuration directories shall be named in the style of filename.conf. Files in /etc/ override files with the same name in /run/ and
/lib/. Files in /run/ override files with the same name in /lib/.
Packages should install their configuration files in /lib/. Files in /etc/ are reserved for the local administrator, who may use this logic
to override the configuration files installed by vendor packages. All configuration files are sorted by their filename in lexicographic
order, regardless of which of the directories they reside in. If multiple files specify the same option, the entry in the file with the
lexicographically latest name will take precedence. It is recommended to prefix all filenames with a two-digit number and a dash, to
simplify the ordering of the files.
If the administrator wants to disable a configuration file supplied by the vendor, the recommended way is to place a symlink to /dev/null
in the configuration directory in /etc/, with the same filename as the vendor configuration file. If the vendor configuration file is
included in the initrd image, the image has to be regenerated.
EXAMPLE
Example 1. /etc/modules-load.d/virtio-net.conf example:
# Load virtio-net.ko at boot
