I don’t believe there is.a way to hid the fact that you are using a VM with virtual box. At least that’s what I remember finding when I looked into it a couple of weeks ago. If I am wrong, I hope someone will correct me, because I prefer virtual box over VMware. If it wherent for this one missing feature.
I use backbox lixux …they cant syskey a linux box …play dumb long enough, do it …ive had several 45min sessions, do what you want but linux is baller, just play dumb “im not good w/ computers” …youll figure it out, backlslater
