In this session we will cover the basic concepts of BoxGrinder, with discussion of techniques and use-cases that illustrate how best to utilise BoxGrinder's powerful feature-set. Finally, we will work through a live example, from text definition to a running virtual appliance.
Ganeti is a sophisticated system (~60,000 lines of python code and ~6,000 lines of haskell code) for managing clusters of virtual machines (based on KVM, Xen or LXC). In this talk we'll describe the internal subsystems and how they interact with the open source virtualization software it manages. Attendees will gain insights on how Ganeti works and how it can be customized to fit their environment.
The talk is about operating system virtualization technology known as OpenVZ. This is an effective way of partitioning a Linux machine into multiple isolated Linux containers. All containers are running on top of one single Linux kernel, which results in excellent density, performance and manageability.
This talk will firstly discuss the impossibility of using current APIs efficiently (via benchmarks on a diverse set of hardware (from many-core AMDs to the experimental Intel SCC). Finally, I will describe our work on introducing a hierarchical name system and extended socket API that adds support for automatic transport selection and reconfigurable sockets. This permits many NUMA-related optimisations on single hosts, for VMs to switch to shared memory communication if on the same physical host, and for seamless network-wide protocol upgrades to multi path TCP or TCPcrypt.
