      Installed Qubes and is running. I like the concept but I kind of at the point of "Okay, what now?". I attempted to install the Brave browser and keep getting blocked. My best guess right now is outside firewall because we're not a Linux house at all. Attempted to do a Yum update and discovered that yum has been deprecated and is now going to DNF. WTF?

        DNF replaced YUM in the Fedora world a few releases ago.

        YUM is ancient.

          The DNF commands are essentially the same. The only one I've noticed a difference on was yum localinstall package.rpm. It's now dnf install ./package.rpm.

          And yum-cron is now dnf-automatic. That's about the only differences you see from a high level.

            One other thing that struck me. For some odd reason DNF usually requires the full path to do a provides search. So an easy way to fix that is

            dnf provides "*"/command
            

            The asterisk is the wildcard for any path. So an example

            [jhooks@megatron ~]$ sudo dnf provides "*"/nslookup

              So I was able to get passed dnf by discovering that once you connect it to the Internet that it reaches out and pulls the updates. Updates are pretty simple to manage, as long as you manage the vm appropriately.

              All default VM's are updated and I am in the process of installing Kali. However, I have run into another problem. One of the reasons why I wanted Qubes was to be able to setup and learn CentOS & Freepbx, along with several other server systems. When I go to install a server, I receive anews error trying to create a templateVM or to make it a standalone. It doesn't have the specs for an x86_64 HVM.

              Got any suggestions?

                    @NerdyDad You can't build it a standalone either?

                      @NerdyDad https://www.qubes-os.org/doc/building-non-fedora-template/ that's for creating your own template not that easy to create.

                      But it should let you build it as standalone and HVM

                      Instead of using Qubes, did you try just using a regular linux distro and using KVM with virt-manager.

                        I think that you have the wrong tool for the job. Others are correct, you just want a normal KVM install. Qubes is the wrong tool here.
