LAB: Software requirements.

You’ve got two main options:
– grab a DVD of RHEL6 or CentOS6,
– use Internet to download the equivalent iso distributions.

If you follow the second option, choose your CentOS mirror and get a copy of the last version of Centos 6 x86_64.
I personally chose to download the LiveDVD version (/pub/centos/6.4/isos/x86_64/CentOS-6.4-x86_64-LiveDVD.iso) for the KVM host and the 2-DVD version (/pub/centos/6.4/isos/x86_64/CentOS-6.4-x86_64-bin-DVD1.iso & /pub/centos/6.4/isos/x86_64/CentOS-6.4-x86_64-bin-DVD2.iso) for the VM repository.
