[vmware-iso] Wrong parameter in .vmx on Big Sur / VMware Fusion 12.2 Pro

[devops-42]

Overview of the Issue

I tried to create a Linux VM (Fedora) using packer, kickstart and VMware Fusion 12.2 Pro. The Linux VM should run in a separate network vmnet5 I created before in VMware Fusion. After kicking the VM gots an IP address from the NAT network (Share with my Mac). But according to the VM settings the network adapter has been configured to use vmnet5.
When looking into the .vmx file created I saw, that there's a parameter:

ethernet.bsdname=en0

which refers to the main ethernet adapter of the Mac. If I remove this line, the VM booted into the right network.

Reproduction Steps

• Create a packer file fedora.json (see below)
• Create necessary kickstart files and place them into path
• Start packer builder:

PACKER_LOG=1 packer build fedora.json 

• Wait until VM is up and provides an emergency shell
• Verify IP with ip a

Packer version

packer version:

Packer v1.7.8
