CloudStack Collab Conference 2014

The 4.4 release of Xen Project is no minor "point" release of software. This latest release from the original enterprise-ready Open Source hypervisor contains some important additions, most notably the arrival of the new experimental PVH mode. Dubbed Paravirtualized Hardware mode, PVH represents a new leap in paravirtualization: Paravirtualization within a hardware container, resulting in potentially higher performance for your cloud. Beyond PVH, Xen Project is also making inroads in other areas. Recent enhancements include additional support for the ARM architecture, improved FreeBSD support, additional libvirt support for the libxenlight toolstack, the release of Mirage OS 1.0, and more. The presentation will conclude with an overview of planned future enhancements, as well as a summary of some of the newest technologies to become interested in clouds built on the Xen Hypervisor.

A virtualization layer is at the heart of all CloudStack clouds, but the choice of hypervisor can have direct impact on the capabilities of a given cloud. CloudStack natively supports XenServer, Oracle VM, KVM, LXC and with CloudStack 4.3 Microsoft Hyper-V was added, but when designing a cloud selecting the correct hypervisor goes far beyond a simple preference. In this session we'll cover how storage, network and even desired CloudStack features combine forming a preferred hypervisor set for your cloud.
