virt-manager features and specs

  • User-friendly Interface
    Virt-manager provides a graphical user interface that makes it easier for users to manage virtual machines, especially for those who are less comfortable with command-line tools.
  • Integration with libvirt
    Virt-manager seamlessly integrates with libvirt, allowing users to manage different types of hypervisors such as KVM, Xen, and QEMU, among others.
  • Snapshot Management
    The tool supports snapshot management, allowing users to take and manage snapshots of their virtual machines easily.
  • Resource Allocation
    It provides an intuitive way to allocate resources such as CPU, memory, and storage to different virtual machines, making it easier to optimize performance.
  • Remote Management
    Virt-manager allows users to manage virtual machines on remote hosts via SSH, giving flexibility in managing VMs across different physical machines.

Possible disadvantages of virt-manager

  • Linux-centric
    Primarily designed for Linux users, meaning Windows and macOS users may face challenges or limited functionality when using virt-manager.
  • Performance Overhead
    Graphical tools like virt-manager may introduce a slight performance overhead compared to managing VMs via direct command-line tools.
  • Complexity for Large Environments
    While virt-manager is great for small to medium setups, managing a large number of virtual machines can become cumbersome due to the limitations of the GUI.
  • Limited Advanced Features
    Some advanced features available in command-line tools or other sophisticated management solutions may not be fully supported in virt-manager.
  • Dependency on libvirt
    Its functionality heavily depends on libvirt, making it less versatile if you need to manage hypervisors not supported by libvirt.

OpenStack features and specs

  • Open Source
    OpenStack is open source, which means there is no licensing fee and a broad community of users and developers contributes to its development and support.
  • Flexibility
    It supports a wide variety of hardware and software, allowing organizations to customize their cloud infrastructure to meet specific needs.
  • Scalability
    OpenStack can scale horizontally, allowing organizations to add or remove resources as their needs change, effectively managing large pools of compute, storage, and networking resources.
  • Vendor Neutrality
    Being vendor-neutral, OpenStack offers flexibility to avoid vendor lock-in and choose from a wide range of compatible technologies and service providers.
  • Community Support
    A large and active community provides extensive documentation, forums, and support, which can be very helpful for troubleshooting and development.

Possible disadvantages of OpenStack

  • Complexity
    Setting up and managing OpenStack can be complex and requires a significant level of expertise, which may necessitate specialized training for staff.
  • Performance Overhead
    Being a feature-rich platform, it often involves more performance overhead compared to other simpler, more streamlined services.
  • Resource Intensive
    OpenStack can be resource-intensive in terms of CPU, memory, and storage, which might not be suitable for all organizations, especially smaller ones with limited resources.
  • Interoperability Issues
    Integrating OpenStack with existing systems and third-party tools can sometimes present challenges, especially when dealing with legacy infrastructure.
  • Evolving Platform
    The platform is constantly evolving, which can be both a pro and a con. Keeping up to date with the latest releases and changes can be time-consuming and may require ongoing maintenance.

  • Locked in: the inextricable dependency on VMWare
    Libvirt is a C library developped by RedHat under the terms of the GNU LGPL license, that provides a generic API that abstracts the bits and bytes of the underlying hypervisor, networking and storage technologies. Using libvirt generic API permits to benefit from a large ecosystem of open source software and tools. As an example, it is possible to use the virt-manager client to create and manage virtual... - Source: dev.to / about 1 year ago

  • Proxmox VE: Import Wizard for Migrating VMware ESXi VMs
    I would love to see a serious comparison (features & performance) between VMWare ESXi, Proxmox VE and let's say a more stock RHEL or Ubuntu. And maybe even include FreeBSD/bhyve. Because yes, in terms of core functionality it should be in the same ballpark. And in terms of UI, Virtual Machine Manager [0] was not that bad.

    Shout out to https://virt-manager.org/ - works much better for me, supports running qemu on remote systems via ssh. I used to use this all the time for managing bunches of disparate vm hosts and local vms. - Source: Hacker News / over 1 year ago
