    KVM, anything else is garbage.

    It doesn’t matter for my purposes but if I were a provider I would definitely offer KVM

  • There is no doubt that I definitely choose KVM

  • OpenVZ and LXC are not hypervisor.

    Did you need post count or something?

    Creator of microLXC says microLXC is garbage.

    No, I'm just wondering to see what I should provide as I currently mainly provide KVM only.

  • I prefer the KVM & OVZ (depend of the usage type). Usually use KVM based VM's for my main machines, and OVZ for side and small tasks. Truly I like both :)
    I do not prefer LXC because of small and irritating 'deficiencies'.

  • kvm ovz

  • If you getting KVM box with OVZ or LXC price, why not ??

  • VirtualBox

    From a provider, KVM is best. VMWare and Xen are fine too. Definitely not OpenVZ.

    For my own use cases, LXC (which is containerization rather than virtualization) is useful, but these days I mainly just use Docker containers instead.

  • kvm

  • I'm using VPS of OVZ as my main for now. By the way, the tool running on VPS is run on docker container. I'm thinking of moving to KVM VPS on LXD container by April of this year.

    OVZ6 worked well for me for over a decade but I only consider KVM for new servers now. I don't know about OVZ7 but OVZ6 was never as stable as KVM. I also ran into incompatibility issues once in awhile that would cause headaches.

    Openvz. I would pay more for it. It uses less resources and you can upgrade/downgrade disk, cpu, memory without rebooting! It's very useful for scaling projects where uptime is critical

  • KVM only

  • Surprised there aren’t any systemd-nspawn providers yet

    KVM supports encryption, so ovz would only be an option if you trust your provider to not be sniffy.

    It is easy for a provider to bypass encryption in KVM, there are even off the shelf scripts to do so

    I didn't know that it can downgrade disk, that's actually quite nice!

    I read about it and find it interesting.
    Shall I be the first to offer such a service?

  • KVM without a doubt

  • I no doubt choose KVM :)

    Less resources is the one and only advantage. Not worth the extra hassle of learning all the proprietary things about it. With KVM being the defacto standard there is a lot more info how to do everything. With cheap SSD drives the resources issue isn't that big a deal anymore.

  • Both OpenVZ and LXC are container technologies and aren't really virtualization. It's really in the same league as FreeBSD jails or Docker.

    KVM is the same league as Bhyve, HyperV, Xen or VMWare instead.
