Dell PowerEdge 2970
Install Centos 7 x64 minimum.
[left as default]
vi /etc/sysconfig/network-scripts/ifcfg-eno1
[change onboot=yes]
service network restart
yum update -y && yum install nano logwatch ntpd ntpdate && reboot
nano /etc/hostname
yum group install 'Virtualization Host'
chkconfig libvirt-guests on
yum install virt-manager xauth
nano /etc/sysconfig/network-scripts/ifcfg-br0
[delete auto created virtbr0]
[create vm with defaults - centos 7 x64 minimal]
virsh autostart centos7.0
[debug, pull out hair, email centos list, remove ipv6, remain puzzled]
