I would to use Microsoft Hyper-V technology VM for hosting Vagrant box VM.
I create my guest VM with vagrant and hashicorp/bionic64 box. My machine is created and correctly running (access SSH by vagrant ssh command)
But I want to access into this with static IP.
Dealing with this tuto : HyperV static IP I want to create a new Virtual Switch but I have this error :
Sorry the screen is in french langage. It tell that : Error when application modifications of property commutator virtual. Failed when adding connexion of commutator virtual ethernet Failed of the sync of ethernet port Impossible to create a file already exist.
What is this already existing file ? Why HyperV can create my virtual switch ?
And finally when the error throw I lose my WiFi connexion into my host windows 11. I need to restart for restoring connection.
