Nested RHEV-h Hypervizor – Virtualization Lab Setup

RHEV can be implemented various ways, from bare metal or from the RHEL OS itself.

Setting up separate hardware servers for each lab can become costly if you are doing it from your home lab… which is why I typically do nested test labs within ESXi or CentOS KVm. This walk-through is for setting up RHEV-h nested on ESXi 5.5. As it will not work with ‘normal’ RHEL Guest settings. Within vSphere, create a new VM and under Operating System type select the following:

Guest Family – Other Guest Version – Other (64-bit)

After that option, go fwd, then the next custom option you will select is LSI Logic SAS for the SCSI controller and then enable VHV under the CPU options.

Next, you will need to add these two advanced virtual machine settings:
vcpu.hotadd = false
apic.xapic.enable = false

Add the RHEV ISO as a CD mount, and select ‘connect upon boot’ check box option.

Power on the VM and wait for the red RHEV loader screen to boot up.

Once the VM starts up, you will be presented with install/upgrade options, you then need to hit the TAB key. This will display a line that shows the installation parameters; within these parameters remove the quiet option from the line and then hit enter to start a visual installation.

If you’ve made it this far then you should be able to complete the installation with no problem. If you hadn’t set the previous options on the VM configuration file then you would not boot into the RHEV-h installation screen, you would simply see an error on the console or the red screen would hang before going into installation.

Config Screen for RHEV-h (Type 1 Hypervisor) – This screen is what you will see after boot-up. THis is where you will configure your network, hostname, RedHat Subscription and add the RHEV-h host to the RHEV Management host via the oVirt engine.
