I am looking to buy a new desktop with a primary purpose of teaching myself RedHat so i can pass the certs. The idea is to run windows 10 host OS and then multiple instances of CentOS through Virtualbox. I recently bought an Acer Aspire GX-281 and after talking with them they refuse to help me update the firmware to allow for hardware virtualization. I am trying to return the Acer and buy something that will work for my purposes. I am currently investigating this Dell https://www.newegg.com/Product/Product.aspx?Item=1VK-0001-16N22 and I figured I would ask you all instead of just assuming that any thousand dollar computer would come with at least an option to enable hardware virtualization since it’s 2018.
