To disable and remove firewalldSince we're forced to use a Windows machine as the main VM host, issue the following commands:systemctl disable firewalldsystemctl stop firewalldyum remove firewalldwe're going to have to set up nested virtualisation. Luckily that's not too difficult.

To * Change the settings for your c7host to have at least 4GB of RAM, and enable "Virtual Intel VT-X/EPT or AMD-V/RVI" under VM/Settings/Processors.* Install the following packages: qemu-kvm qemu-img virt-manager libvirt libvirt-python libvirt-client virt-install and virt-viewer bridge-utils* Make sure (using <code>systemctl enable </code>) that the libvirtd service starts at boot.* Those will include both the IPTables servicesKVM hypervisor and Virt Manager, issue which is a graphical tool used to administer it.* Create a new virtual machine with the following commandssettings:** Will be installed from the network: https://mirror.senecacollege.ca/centos/7/os/x86_64/ or http://mirror.netflash.net/centos/7/os/x86_64/** 2GB of RAM** 10GB of disk** NAT for networking** hostname lin1** Minimal install After you're done - you'll have a command-line-only CentOS machine (lin1) running inside a graphical CentOS desktop (c7host). = PART 2: IPTABLES = CentOS comes with firewalld installed by default. We will not be using that, instead we'll do all our firewall work with iptables. Therefore we'll need to uninstall firewalld and install iptables management tools: * Use systemctl to stop firewalld and disable it from starting on boot.* Use yum to uninstall firewalld and install iptables-services* Use systemctl enable iptablessystemctl to start the iptablesservice and configure it to be started on boot.
