.NET Workload Troubleshooting

To install the maui workload, you have two options:

dotnet workload install commands
Visual Studio on Windows can install .msi files for each workload pack. Note that the concept of a "Visual Studio workload" is different than a ".NET workload".

VS for Mac's installer and updater use dotnet workload install commands. It's considerably simpler to get a Mac machine to a clean state.

1. Environmental information

OS: Ubuntu 20.04.2 LTS (GNU/Linux 5.8.0-59-generic x86_64)
Network: 192.168.xxx.0/24
Ubuntu multipass host machine IP: 192.168.xxx.yyy(static IP)
NIC: enp2s0(bridge host NIC)
Bridge NIC:br0

2. Prerequisites

Using Multus CNI in K3S

By default, K3S will run with flannel as the CNI and use custom directories to store CNI plugin binaries and config files(You can inspect the kubelet args K3S uses via journalctl -u k3s|grep cni-conf-dir). So you need to configure that properly When deploying Multus CNI.

For example given the official Multus manifests in https://github.com/intel/multus-cni/blob/36f2fd64e0965e639a0f1d17ab754f0130951aba/images/multus-daemonset.yml, the following changes are needed:

volumes:
 - name: cni

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!
