Pricing and Cost Advice
  • "It is free for everyone."
  • "The price is fair compared to others. But in our local market, it's a problem to get budget approval from management. That's why they are trying to get those products so we can give them the price benefit. But if you consider the international market or other products, it's sometimes better than their price."
  • "We had some problems with the licensing."
  • "KVM is priced reasonably."

    Overview
    KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko.
    OpenVZ is a container-based virtualization for Linux. OpenVZ creates multiple secure, isolated Linux containers (otherwise known as VEs or VPSs) on a single physical server enabling better server utilization and ensuring that applications do not conflict. Each container performs and executes exactly like a stand-alone server; a container can be rebooted independently and have root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files.
