Use NoMachine to access VM

less than 1 minute read

Published:

A GUI is often needed when using VMs and ssh’ing into shell is insufficient. Windows Remote Desktop offers a ssh-based remote access method, but has a really slow GUI. I’ve found NoMachine to have a much faster response (which saves a lot of headaches).

You need NoMachine on both the client and host machines: Install NoMachine

Connecting to a machine over an internet connection has a few more steps, but simply accessing a VM on your host computer is really easy!

Switch to LLVM/Clang compiler for CMake (Ubuntu 22.04 aarch64 on Apple Silicon via Multipass)

if (OPENMP_FOUND
    set (CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")
    set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
endif()
