any luck contacting the people who shared the OVA file with you?
once the VM have started open Virtualbox gui
shutdown the VM
go to settings, change the network driver. not sure which one will work driverless in that version of Windows, I think Intel e1000 is very standard
turn on the VM with vagrant up
does work?
you can add to the Vagrantfile VBoxManage commands that are run before the VM is turned on, check how to use VBoxManage (Virtualbox Documentation) and get the line you want Vagrant to run for you.
And add it to vagrant in the format documented here:
config.vm.provider "virtualbox" do |v|
v.customize ["modifyvm", :id, "--cpuexecutioncap", "50"]
end
