############################ Everything below are my raw notes that I took while attending an unofficial RHCSA training session. I am posting them here in hopes they will assist others who may be preparing to take this exam. My notes are my own interpretation of the lectures, and are certainly not a replacement to classroom training either through your company, or by taking the official RHCSA classes offered through Red Hat. If you are new to the Red Hat world, I strongly suggest looking into their training courses over at Red Hat. ############################
Virtualization
EXAM NOTE: This will not be on the test since the test is on a vm… so they can’t test for it at the time of this writing as far as I can tell.
RHEL6 virtualization is done by:
- KVM - QEMU
To run it, you must be on a 64-bit system and the kernel virtualization extensions much be enabled on the cpu’s. (ie. VT (VMX) and AMD-V (svm))
To get this working, 4 package groups are needed to get this setup:
- Virtualization - Virtualization Client - Virtualization Platform - Virtualization Tools
Libvirt is the management framework used in RHEL6 virtualization.
Interface to libvirt available is:
- virsh : cli - virt-manager : GUI client (Not exactly feature rich...)
