Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"I like that this is an open-source solution. It is very powerful, and it's easy.""If you prefer command-line, there are all kinds of command-line options.""The initial setup was simple.""What I like most about KVM is that it's very easy to use. Everything is built-in, even when writing command lines.""Scaling the solution is easy. You just have to add more hardware.""This solution is open source and easy to configure.""The most valuable feature is hypervisor. I can host at the same time different operating systems in Linux Windows.""If you are a Linux desktop user, KVM is the solution to go with if you have to start virtual machines with Linux or other operating systems with almost zero extra configuration needed."

Cons
"KVM is very difficult to manage and run on daily operations.""I have encountered difficulties in getting the tool's documentation.""Monitoring and resolution could be improved.""The only negative aspect of needing hardware support is a fully functional KVM can be dropped. It would be nice if the support for other platforms, like ARM or Risk, were as good as the x86 one. However, with the democratization of Chromebooks based on these chips and mobile devices, it will not take long for that to happen.""In our setup, we do not have any dashboards or orchestration, and it is hard to manage. We have 25 gig network cards, but the software driver we have only supported 10 gigs.""The KVM tech support is really bad. They are not very responsive.""Technical support is not top-notch.""One problem I have is that it's not very scalable when it comes to resizing the VM disk dimensions. For example, if you have initially set a virtual drive to 10 GB and you want to upgrade it to 15 GB, it's not that easy."

More KVM Cons →

"I think that this solution should be more user-friendly.""I find the solution to be incredibly unstable, constantly falling over and not working properly.""The installation is difficult and could be improved.""Oracle VMs don't have a solid web interface of their own. This is an area where Oracle is lagging behind. Now, we use headless servers, install Oracle VMs, and manage them remotely. We could use phpVirtual Box, but it is a third-party solution. A lot of people contribute to it, and it's not authenticated by Oracle. As a result, I don't find it to be a good option. Therefore, I would like to see Oracle offer an extension pack or a licensed version that fixes this problem.""It would be good if we could use Hyper-V Windows subsystems with Linux and VirtualBox on the same instance. Currently, to be able to use VirtualBox, we have to restart the machine into an instance of Windows where Hyper-V is disabled, which is understandably very inconvenient.""The AI and the UI could be improved. The user interface is a little outdated and the AI is not very attractive.""Basically, the GUI and command-line interface need improvement.""The communications setup lags. It does not connect properly so the batching and networking is a bit slow."

    Overview

    KVM stands for Kernel-based Virtual Machine, which is an open-source virtualization technology that is embedded in Linux. KVM allows users to seamlessly transform their Linux system into a hypervisor that, in turn, will enable a host machine to run numerous, isolated virtual environments or virtual machines (VMs).

    KVM is part of Linux. Users with Linux 2.6.20 or newer already have KVM. As KVM is already a component of the current Linux code, it automatically improves with every new Linux fix, feature, or upgrade. So KVM users are always current and up to date.

    KVM automatically transforms Linux to a type -1 (bare-metal) hypervisor. All hypervisors need operating system components, such as a process scheduler, I/O stack, device drivers, memory manager, and more, to run a VM. KVM already has these components embedded, as it is part of the Linux kernel. Each VM is generated as a basic Linux proces,s which is maintained by the standard Linux scheduler, with dedicated hardware such as a graphics adapter, memory, disks, network card, and CPUs.

    KVM Key Features:

    KVM has many valuable key features. Some of its most useful features include:

    • Storage: KVM has the ability to use any storage protocol supported by Linux, including network-attached storage (NAS) and some local disks. Multipath I/O can be utilized to provide redundancy and improve storage. Disk images use thin provisioning, ensuring storage is used on demand. KVM is also able to use shared file systems, enabling VM images to be shared on multiple hosts.
    • Hardware: KVM is able to use a vast number of Linux-certified supported hardware platforms. As hardware vendors routinely contribute to kernel improvement, the most up-to-date hardware features are generally quickly added to the Linux kernel.
    • Memory: KVM effectively utilizes the memory management features of Linux, such as kernel same-page emerging and non-uniform memory access. The memory of a VM can easily be switched, supported by large volumes for improved performance, then backed by a disk file or shared.
    • Migration: KVM actively supports live migration so users have the ability to move any running VM between physical hosts with no downtime.
    • Security: KVM uses a blend of secure virtualization (SVirt) and security-enhanced Linux (SELinux) for improved VM security and isolation. SELinux determines security boundaries surrounding VMs. sVirt expands SELinux’s processes, permitting Mandatory Access Control (MAC) security to be used for guest VMs and preventing any manual labeling issues.

    Reviews from Real Users

    “The most helpful aspect of KVM is the fact that the interface is so minimal. It includes just what you need to set up the VMs and manage them, and it's very simple to do so. KVM, as a native virtualization solution, is a complete and fully adequate system for small businesses that need to reduce costs, and also to make maintenance easier. “ - Georges E., Business Engineer and Consultant at All-Tech

    “The most valuable feature of KVM is the hypervisor environment and how we can configure it with ease. Additionally, the interface is intuitive.” Sonu S., Senior Solution Architect at Micro Focus

    Oracle VM VirtualBox Features

    Oracle VM Virtual Box provides many value-added features.  Some of these features include:

    • Consolidation: Oracle VM VirtualBox makes it easy for users to seamlessly run numerous virtual machines on a small number of hosts and will also facilitate comprehensive balancing of the loads between VMs. This helps to minimize and consolidate the hardware needed throughout the organization.
    • Diagnostics: VirtualBox provides excellent testing and disaster recovery. Users can use the virtual hard disk like a container. This container can be copied, frozen, backed up, or transported between hosts. Using the virtual machines (VMs), users can easily test multi-node network services for any networking, software configuration, or operating system issues.
    • Snapshots: Using snapshots, users are able to save or freeze a specific state of a VM and choose to revert back to the protected state if/when they desire. Users are able to make changes or experiment within the computing space. Should a problem arise, users can revert back to the selected snapshot; this makes the need for frequent backups and restores unnecessary.
    • Flexibility: The solution makes it easy to run different operating systems (OSes) at the same time. Users can run software designed for one OS on another OS. For example, users can easily run Windows on a MAC and not have to perform a reboot. As users can configure the kinds of virtual hardware to be presented with each OS, there is greater flexibility on which OS can be selected, and users can even choose older OSes or ones that are not currently supported by the original OS.
    • Cost-effective: Virtualization with Oracle VM VirtualBox enables users to considerably minimize overall costs by reducing the amount of hardware needed and the associated expenses of running the physical machines throughout an organization. This tremendous cost savings results in ROI being achieved in a very short period of time.

    “Oracle VM VirtualBox is easy to use and does not require much training. It uses fewer resources. Teams using new operating system releases can quickly test and implement. This would make the development of new software releases faster and easier. It also helps users to write the program, test, and support it on multiple platforms. It has a good community as it is open-source.” - Satishbabu G., Oracle ACE

    “It is easy to use and does not require complex knowledge. It uses less resources, which is a requirement as it is used to onboard hardware with very little resources available.” - A PeerSpot user who is an IT Architect - AI at CGI
