Launch a VM

From r83x5u09,

cd /var/lib/libvirt/images
cp centos7_15g.qcow2 chef.qcow2; cp centos7_15g.xml chef.xml    

Modify xml definition to reflect template name, VM name and disk name, then

virsh create chef.xml

Set hostname

hostnamectl set-hostname chef

Assign IP address according to IP Planning

nmtui

ifcfg-eth0 Sample

[root@chef network-scripts]# pwd
/etc/sysconfig/network-scripts
[root@chef network-scripts]# cat ifcfg-eth0

Install Chef

wget https://opscode-omnibus-packages.s3.amazonaws.com/el/6/x86_64/chef-server-11.1.3-1.el6.x86_64.rpm 
yum install chef-server-11.1.3-1.el6.x86_64.rpm rubygems    

Scratch all the above about CentOS 7 as Chef server doesn't support it up to this document being written

Update Hostname and Assign IP Address according to IP Planning

[root@chef ~]# cd /etc/sysconfig/network-scripts/
[root@chef network-scripts]# pwd
/etc/sysconfig/network-scripts
[root@chef network-scripts]# cat ifcfg-eth0 
DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=none
IPADDR=172.16.0.32
NETMASK=255.255.0.0
GATEWAY=172.16.0.21

Setup yum.repos.d for CentOS 6.5

Update /etc/hosts and Hostname

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.0.32     chef

Install rpms

yum install chef-server-11.1.3-1.el6.x86_64.rpm rubygems

Start Configuration

chef-server-ctl reconfigure    

If the task doesn't finish successfully because of hostname not able to be resolved, just disable /etc/resolv.conf Login as "admin"
