Need suggestion on RHCVA exam

I was thinking about starting to prepare for this one and is it ok for the exam to study virtualization guide from fedora documentation.
I think that guide and lots of practice should be enough for this certificate. Any suggestion?

No, that's not really the focus you need. Many of the RedHat certs contain a significant amount of sales pitch in them, and as such this is a certification for the RHEV platform, not just the freely available constituent parts. You need to know RHEV-M (windows management console) as mush as RHEV-H (KVM + tools), so only knowing about kvm, qemu and virt-manager won't get you there.

Definitely not enough. It's just different.
The more appropriate guide for preparing RHCVA exam is this RHEV documentation.

I'm not a RHCVA holder, nor did I take the exam, but have worked on several implementation of RHEV, IMO it's not really that hard. Once you get the concept and being comfortable with RHEV-Manager, then things should be easier. There's no need to type anything after installation and RHEV-Host successfully registered with the RHEV-M. In fact, the root filesystem of the RHEV-H is mounted read-only. Even multipathing is configured automagically; they should provide a working storage to work with, but please don't count on me on that.

A lot of practice would help, but be prepared for the requirements; the hard part is the hardwares.

To build a lab for studying, you'll need 4 systems;
1. Windows OS, 2008R2 recommended, for the RHEV-M. The current version of RHEV-2.2 does not support Manager console from OS other than Windows. (Ha!)
[2&3] Intel-VT/AMD-V 64bit capable hardware for the RHEV-Hosts. You need to learn how Live Migration and Failover process occurs, so there must be at least 2 RHEV-Hosts.
4. External storage server. This can be an NFS, iSCSI or FC-based NAS/SAN. Openfiler works fine for this purpose. Unlike VMware ESX, RHEV does not have options to install VMs on its local disk.

The software itself is not free, and not open source yet, so there's no equally free version of RHEV outside RHN.

From the brainware side, you'll need a dogged determination to comprehend the whole subject. One could easily get lost in the myriad aspect of RHEV's configuration, especially when it comes to its step-sequenced procedures. It's almost a total point-and-click activity, you just have to know what to click, and when.

Good luck.

Thanks a lot guyz..
I don't have the luxury to setup that lab yet so better start it when I will be able to manage that... until then lets try to learn something else.
