RHCVA Self-Preparation environment
Is it possible to create the RHEV's environment on a single laptop with enough resources for preparing for RHCVA. Like RHEV-H can be the base machine with RHEL 6 as the host and we can create a VM and install and configure RHEV-M and then connect the host to the RHEV-M. will it work??
just from preparation point of view.
Thanks

You have two options:
- Use rhevm-setup-plugin-allinone.
# yum install rhevm-setup-plugin-allinone
Use the setup command from the above rpm. Don't remember the exact name of the command.
- Use nested vms under libvirt+kvm as hypervisors. Just search for "nested kvm" to see how to configure that.

Sorry to hijack this discussion: I tried the 'nested kvm' option, but experienced it was very unstable (hypervisor lockup, qemu running 100% cpu) with RHEV3.1 (not sure if I have tested this on RHEL6.4 host/hypervisor, this was just a few weeks ago). Besides: I had to use Fedora as the host for libvirt+kvm because RHEL didn't support /sys/module/kvm_intel/parameters/nested, but then again: I did not yet test RHEL 6.4 Host or Hypervisor)
I didn't read the release notes of RHEL 6.4. Where there any improvements with nested kvm in RHEL 6.4? If I get the hardware available, I will try again.

I think the all-in-one install is a great way to learn your way around in RHEV, though working with storage will get you more familiar how RHEV storage domains work.
