Kernel-based Virtual Machine (KVM) vs. Oracle Linux

Kernel-based Virtual Machine is very well suited when one needs a single-node virtualization host or needs to build a complex demo setting on their own notebook (e.g. when demonstrating solutions to a customer).

As a result of the migration from Red Hat Enterprise Linux to Oracle Linux, overall application performance was improved significantly. Oracle Enterprise Linux is pretty much based on the Red Hat Linux code, although it receives faster and more regular updates from Oracle. They have better security configurations. However, it is also missing a lot of packages that are usually available in other distributions.

• Lightweight built-in implementation for all *nix based OS.
• Easy to deploy and manage VMs.
• Freeware (is you are using a free OS).

• Oracle Linux is a clone of Red Hat Linux, a well-known version of Linux and is very stable. This helps in maintaining fairly error-free systems.
• The operating system kernel can be updated without having to reboot the system, a potential time saver.
• Oracle Linux comes in fairly easy to implement packages that work well with Oracle databases.

• KVM itself doesn't ship with a management interface
• KVM itself is a bit complicated to handle
• KVM needs Qemu to virtualize Windows guests

• TigerVNC needs some fine tuning in Oracle Linux 8.4.
• AutoTuning of Kernal Parameters for Oracle Databases based on the available hardware resources.
• Embedded IPA Solutions to manage large number of Oracle Linux Systems.
• Simple commands for LUN management.
• Proactive SELinux policy violation message to administrator's mailbox.

It does the job and stays out of the way. The specifics of usability relies on the implementation, but with things like Icarus and libvirt, things are standardizing nicely.

Quick & [on-point] response is what I would say for the support team. There hasn’t been trouble ever since we get in touch with them and ask for help for any major or minor trouble we have been facing. Moreover, the team is very accurate with their solutions and detailed orientated. With such [a] high-performance application and agile environment, a team as such is great at hand.

The key points why I made my decision for KVM in comparison with VMWare are: Freeware software (I am using an Ubuntu server OS), Fewer resources usage, vSwitch using that provides the ability to configure dot1q trunks to/between VMs, Stability, and simplicity of using/troubleshooting, Well-known interface (for Linux geeks).

Oracle Linux became the obvious choice amongst its competitors due to its speed, agility, flexibility, and support from Oracle engineers. The ease of use was one of the major reasons for choosing Oracle Linux over the above-operating systems. Also, the cost of operations, management, and retention were significantly quite low. This made Oracle Linux a very easy and quick choice for our organisation.

• Capital expenditure costs are low, because is open-source and free
• Operational expenditure costs are medium because it's necessary [to have] an IT team with experience in Linux
• First step to the virtualization world. Wake up, we are in the 21st century

Incentivized

• Zero-downtime automated patching for kernel, hypervisor, and critical user-space libraries.
• Optimized–out of the box–for Oracle software.
• A single support offering includes Linux, virtualization, management, HA, and cloud-native computing tools.
• Available on-premise, in the cloud, and as Autonomous Linux.
• The system has a graphical and command-line interface, which makes it very complete and superior to other similar products.
• Security
• Compatible with multiple types of hardware. If we need to upgrade our hardware, the idea of not having to change OSs or platforms is a huge benefit.
• Managing Memory usage.
