+    Instructions for setting up warewulf development environment under KVM
+
+1. Create Centos 7 development virtual machine under KVM
+
+    # KVM is running on server called master1 which is not my desktop
+
+    ssh -X master1
+
+    # On master1 server
+
+    wget -P /global/downloads/centos http://mirror.mobap.edu/centos/7.8.2003/isos/x86_64/CentOS-7-x86_64-Everything-2003.iso
+
+    qemu-img create -o preallocation=metadata -f qcow2 /global/images/centos-7.qcow2
+
+    # install wwdev Centos 7 development VM
+
+    sudo virt-install --virt-type kvm --name centos7-wwdev --ram 8192 \
+       --disk /global/images/centos-7.qcow2,format=qcow2 \
+       --network network=default \
+       --graphics vnc,listen=0.0.0.0 --noautoconsole \
+       --os-type=linux --os-variant=rhel7.0 \
+       --location=/global/downloads/centos/CentOS-7-x86_64-Everything-2003.iso
+
+    # Complete installation using virt-manager
+
+    # To start virt-manager on non-local server
+
+    ssh -X qmaster1
+
+    sudo -E virt-manager
+
+    # Login to VM and install @development group and go language
+
+    ssh root@wwdev
+
+    # Disable selinux by modifying /etc/sysconfig/selinux
+    vi /etc/sysconfig/selinux
+
+        SELINUX=disabled
+
+    # disable firewall
+
+    systemctl stop firewalld
+    systemctl disable firewalld
+
+
+
+2. Turn off default network dhcp on server master1
+
+    # shutdown all VMs
+
+    $ sudo virsh net-destroy default
+
+    $ sudo virsh net-edit default
+
+        # remove dhcp lines from XML
+
+    $ sudo virsh net-start default
+
+
+3. Build and install warewulf on wwdev
+
+    ssh wwdev
+
+
+    # Fedora prerequisites
+    sudo dnf -y install tftp-server tftp
+    sudo dnf -y install dhcp
+    sudo dnf install singularity
+
+    # Centos prerequisites
+    sudo yum -y install tftp-server tftp
+    sudo yum -y install dhcp
+    sudo yum install http://repo.ctrliq.com/packages/rhel7/ctrl-release.rpm
+    sudo yum install singularityplus
+
+    # follow README.md instructions
+
+    cd projects/ctrliq/warewulf
+
+    vi nodes.yaml.local
+
+    make -f Makefile.local install
+
+    # build VNFS
+
+    sudo singularity build --sandbox /global/chroots/centos-7 centos-7.def
+
+    vi /etc/warewulf/overlays/generic/etc/sysconfig/network-scripts/ifcfg-* 
+
+        # add IP addresses
+
+    sudo ./wwbuild vnfs
+
+    sudo ./wwbuild kernel
+
+    sudo ../wwbuild overlay
+
+    sudo ./warewulfd
+
