Using Sushy Tools with Libvirt

Add linux user to libvirt group

sudo usermod -a -G libvirt <your-user>
sudo -y install libvirt-devel gcc python3-devel

Login and validate user can execute virsh commands

Overview

Internet connection and DNS routing are broken from WSL2 instances, when some VPNs are active.

The root cause seems to be that WSL2 and the VPN use the same IP address block, and the VPN routing clobbers WSL2's network routing.

This problem is tracked in multiple microsoft/WSL issues including, but not limited to:

Assigning Static IP Addresses in WSL2

WSL2 uses Hyper-V for networking. The WSL2 network settings are ephemeral and configured on demand when any WSL2 instance is first started in a Windows session. The configuration is reset on each Windows restart and the IP addresses change each time. The Windows host creates a hidden switch named "WSL" and a network adapter named "WSL" (appears as "vEthernet (WSL)" in the "Network Connections" panel). The Ubuntu instance creates a corresponding network interface named "eth0".

Assigning static IP addresses to the network interfaces on the Windows host or the WSL2 Ubuntu instance enables support for the following scenarios:

BGP Architectural Components

As we discuss use cases, we can start to distill them down to the building blocks necessary to achieve them. Some of these may be shared across multiple products.
