Proxmox VE vs. Red Hat Virtualization (discontinued)

Proxmox VE is a virtualization platform that provides a range of features and functionalities suitable for various scenarios. Here are some specific scenarios where Proxmox VE is well suited and some scenarios where it might not be the best choice:Well-suited scenarios:Virtualization of server workloads: Proxmox VE is well suited for virtualizing server workloads such as web servers, mail servers, database servers, and other similar applications. Its high-performance virtualization capabilities allow these workloads to run smoothly and efficiently.Hosting multiple virtual machines (VMs): Proxmox VE is ideal for hosting multiple VMs on a single server. It provides efficient resource management, allowing users to easily allocate resources to each VM.Clustered environments: Proxmox VE is a great choice for clustered environments. It supports clustering and can easily manage multiple servers, providing high availability and load balancing for mission-critical applications. Less appropriate scenarios: Limited hardware resources: Proxmox VE requires significant hardware resources to run efficiently. If you have limited hardware resources, it might not be the best choice. Simple applications: If you only need to run a single, simple application, Proxmox VE might be overkill. Other virtualization platforms or even a basic web hosting service might be more appropriate.

Red Hat Virtualization is suitable for small implementation and hosting VMs. However, when you start asking for additional features or enhancements, the engineering team is not the flexible as other engineering teams in Red Hat. It is very likely they will not accept adding features or in the best case. They wouldn't commit to a plan when it is possible to be available.

• ZFS storage out of the box. The integration with ZFS is fantastic. You can easily create pools to store your VM images and data on, and the Proxmox web UI provides an easy way to check drive health, ZFS scrub status, etc.
• Great web UI. Practically everything configurable is available to do so from the web user interface. You'll rarely need to drop to the command line for administrative tasks, unless you want to, in which case you can do that too. The UI also provides graphs and visualisations to help you keep check of how everything is performing.
• Easy to setup a high availability cluster. Although Proxmox VE works perfectly well on a single server, you can also install it on multiple hosts and setup a cluster.
• Uses a Debian core system with an Ubuntu based kernel. This means everything to do with the base operating system is tried and trusted. We use a lot of Debian and Ubuntu installs, so having this run underneath Proxmox VE was an added bonus for us.

• RHV issues/bugs can be reported via Bugzilla to RH support. The service is great and typically responds soon.
• Red Hat distribution integration is seamless as it is integrated into the kernel.
• OpenStack support enables more customized VM templates and network configuration control.

• The web UI does not work as well on mobile devices. It is useable, but a mobile optimised / responsive UI would be nice to have. There is a mobile app, so that may alleviate this issue, but I have not yet tried it.
• Support in the community forums could be better. There are paid support plans, but new users trying out the software will not have access to this. Answers to questions can sometimes be terse, and I can imagine this may put some people off.
• The wiki is a bit hit and miss with certain topics. I've often seen outdated or missing information, and the whole thing looks like it could do with some polish. I'd love to see it opened up for the community to add to.

• Documentation of RHEV needs more improvement.
• RHEV GUI needs a lot of improvements in some versions of RHEV, GUI will not work properly (shows incorrect details of VM ).
• Need fast rollout of patch releases.
• Need good linux Knowledge to manage the RHEVM.

Proxmox VE provides the most capable, yet stable virtualization platform in the market today. Licensing options are also competitive and cost-effective for support, and support is extremely fast and knowledgable of getting issues resolved as quickly and soundly as possible.

The interface is easy to use for most of it, but still lacks screens for some configurations. Also, a few of the screens are not as intuitive as they could be. This is specially true with disk and network configuration, where some graphic/visual representations of the configurations would be very useful

Proxmox VE's ha-cluster functionality is very much improved, though does have a not-very-often occurrence of failure. In a 2-node cluster of Proxmox VE, HA can fail causing an instance that is supposed to migrate between the two nodes stop and fail until manually recovered through the command-line tools provided. Other than this, the HA clustering capability of Proxmox VE has proven to be reliable in 3 or more clustered environments with much less chance of these failures to occur.

Proxmox VE's interfacing is always fast to load, both the Web interface and the command-line tool interfaces. Reporting is practically real time almost all the time, and you can see everything in mere seconds, easily able to identify if something is wrong or it everything is in tip-top shape as always desired

Proxmox Virtual Environment is better, less costly, it has better CAPEX and OPEX, is open source and more robust and flexible.

It is an agnostic product, one can use a PC clone or a high end server to install it, and it works flawlessly on both.

The product has a large life cycle, is stable and has few problems and vulnerabilities than the other propietary products.

Red Hat Virtualization is the best enterprise-level virtualization software for an organization that needs cost-effective and flexible solutions for its environment. We can easily integrate RHEV with other Red Hat software like OpenStack...etc. RHEV is highly customizable software, which helps us to customize our environment. Since RHEV is an open-source tool, we can install it on any hardware. There is no proprietary dependency.

Proxmox VE provides everything you need to quickly add new storage mediums, network and local, as well as networking interfaces, such as using Linux standard bridges and now Open-vSwitch bridges which can be even more scalable than before. Proxmox VE 4.0 dropped support for OpenVZ in favor of the more well supported and native LXC and made an upgrade path to it very simple.

• Due to the open source nature of Proxmox, we have no licensing costs while training our employees
• We've migrated 100% of our clients to Proxmox and have found improved uptime, and flexibility.
• In the 10 years of using Proxmox, we've yet to lose any data or not be notified of backup issues.

• It has had an extremely positive impact on my overall business and has allowed me to utilize and leverage it as an offering to my clients.
• It's an extremely solid, robust, and reliable product built off of KVM Virtualization technology.
• Less expensive solution than VMware and includes more features!
