Red Hat Virtualization (formerly Red Hat Enterprise Virtualization, broadly known as RHEV) is an enterprise level server and desktop virtualization solution. Red Hat Virtualization also contains the functionality of Red Hat Enterprise Virtualization for Desktop in later editions of the platform.
Considering Oracle VDI is not supported by Oracle anymore, and will not receive any future updates, I wouldn't recommend Oracle VDI for most scenarios. Unless your organization is under some strict contractual agreement or there is a feature in Oracle VDI that isn't supported in its modern successors/competitors (haven't come across a feature like that based on my experience), I would recommend using something like VMware Horizon.
RHEV is well suited for organizations that need a cost-effective and flexible solution for their environment. As its vendor-independent software, easily install on any type of hardware. RHEV provides a GUI interface to manage the software, which makes the management of the software easier for the end-user. RHEV is best for non-production or less critical applications. RHEV can be easily integrated with other REDHAT software.
1- RHVM API is pretty slow, especially after creating a VM it is not possible to retrieve the VM details (i.e VM's MAC Address) fast enough, where we need to place a pause in our Ansible Playbook, make the automation process slow.
2- RHV is still using collected to monitor the hypervisors which is deviating from Red Hat policy for other RHEL based applications to use PCP to monitor, which is richer in features.
3- It will be great if it is possible to patch the hypervisors using other tools such as satellite and not only via RHVM.
4- In the past Red Hat used to present patches in the z release (i.e. 4.3.z), and features in the y release (i.e 4. y), but starting from 4.4 that is mixed together wherein the Z release you get both patches and features, that is not good because that requires a lot of time to test when we patch as it includes features as well.
5- Engineering team has to be more reactive when new feature is requested.
The easiest way to describe the performance is like this - when it is working, it works almost flawlessly. When it starts freezing, your day is going to get very interesting very quickly. As I have stated earlier, I used it for one purpose, and it did what I needed it to most of the time, but I did have issues with it.
VMware Horizon does everything that Oracle VDI is capable of doing and offers many more features, and unlike Oracle VDI, it is still receiving constant updates. Oracle VDI was a great solution for enterprise-level management of virtualized desktop when it was getting updates, but now that it won't be getting any, I would put it in the "outdated technology" category.
RHEV is an excellent product, includes more features, is less expensive, and has rock solid reliability and is backed with the best Red Hat Support in the industry. RHEV uses KVM under the hood which is used by all the big players in the industry (AWS, Rackspace, etc) to lower their overall costs and improve efficiency and profits and that's why RHEV is an excellent solution!
