Para quem acompanha o mundo de virtualização e linux, provavelmente conhece ou já ouviu falar no Xen, que já era open source.
No entanto, a Citrix tinha comprado a XenSource (empresa) em 2007, que tem um produto comercial, chamado XenServer que tem como base o Xen, mas tem muitas outras funcionalidades adicionadas por cima, muitas delas baseadas em outros projectos open source, outros nem por isso.
Ora, hoje a Citrix anunciou que lança o XenServer e o XenCenter (consola de gestão feita em C# e que só corre em Windows) para o mundo open source, com todas as funcionalidades do produto comercial*.
A diferença é que o produto comercial tem suporte e o open source não, mas são iguais*.
XenServer 6.2 is now available to download, with the availability of the XenServer "Project Clearwater" Release. Below is an overview of whats new in this XenServer release. XenServer has shifted home, and you can now download it from www.xenserver.org
The big news is:
XenServer 6.2 is available as a free open source virtualization platform for all users
Citrix is also introducing a new XenServer.org community portal
Citrix provides a paid version of XenServer the includes support and maintenance
New CPU socket licensing
New simplified packaging and pricing
The big, big news of the day is that Citrix moves to open source XenServer as part of Citrixs commitment and strategy towards enabling the best platform for providing their customers a path to the cloud. Leveraging their experience as the leader in desktop virtualization and as the dominant virtualization platform in the public cloud, Citrix says it's focused on ensuring a seamless path for customers to migrate their most important workloads to a cloud environment. The first part of this strategy already took place back in April when Xen was moved from Xen.org to the Linux Foundation and became the Xen Project.

Algumas das features:
Xen
XenServer is based on the Xen ProjectTM hypervisor that utilizes a 64-bit architecture to provide near native application performance and unmatched density.
XenMotion
XenMotion eliminates the need for planned downtime by enabling active virtual machines to be moved to a new host with no application outages or downtime.
Xen StorageMotion
Move live running virtual machines and their associated virtual disk image within and across resource pools leveraging local and shared storage. This enables users to move a VM and its VDI from a development to production environment, move between tiers of storage when a VM is limited by storage capacity, and perform maintenance and upgrades with zero downtime.
XenCenter Multi-Server Management
XenCenter provides all the virtual machine management, monitoring and general administration, and general administration functions in a single interface. Administrators can easily manage hundreds of virtual machines from a centralized, highly available management console that installs on any Windows® desktop. The Resilient Distributed Management Architecture distributes server management data across the servers in a resource pool to ensure that there is no single point of management failure.
Site Recovery
Provides site-to-site disaster recovery planning and services for virtual environments. Site recovery is easy to set up, fast to recover, and has the ability to frequently test to ensure disaster recovery plans remain valid.
High Availability
Automatically restart virtual machines if a failure occurs at the VM, hypervisor or server level. Link Aggregation bonds network interfaces for network redundancy and increased throughput.
Host Power Management
Takes advantage of embedded hardware features to lower datacenter electricity consumption by dynamically consolidating VMs on fewer systems and then powering off underutilized servers as demand for services fluctuates.
VM Snapshots
Create snapshots of virtual machines to capture disk and metadata settings for backups, archives and configuration changes.
Memory Optimization
Reduces costs and improves application performance and protection by sharing unused server memory between VMs on the host server.
Intellicache
XenServer is optimized to reduce the overall costs and improve performance of a virtual desktop installation. By using local storage as a repository for boot images and non-persistent or temporary data, XenServer can reduce virtual desktop boot times, decrease network volume and traffic, and save on total storage costs for a
XenDesktop installation.
XenServer Conversion Manager
Automate the process of converting VMware virtual machines into XenServer virtual machines with this simple batch conversion
Heterogeneous Pools
Enables resource pools to contain servers with different processor types, and support full XenMotion, high availability, workload balancing, and shared storage functionality.
Role-based Administration
Role-based administration improves security and enables delegated access, control, and usage of XenServer pools by maintaining a tiered access structure with varying levels of permissions.
Performance Reporting and Alerting
Receive immediate notification with historical reporting of VM performance to enable the rapid identification and diagnosis of fault or failure in the virtual infrastructure.

Novidades nesta versão 6.2:
500 Windows VMs per host and 650 Linux VMs per host
3250 vCPU per host
Traffic reduction between a VM and the Control Domain (Dom0)
Automatic scaling of Dom0 memory and vCPUs based on physical memory and CPU capacity on the host.
Performance and Monitoring supplemental pack is now fully integrated
Clone on boot, which allows rapid deployment of hundreds of transient desktop images from a single source, with the images being automatically destroyed and their disk space freed on exit.
New and improved Guest Support
Microsoft Windows 8
Microsoft Windows Server 2012
SUSE Linux Enterprise Server (SLES) 11 SP2 (32/64-bit)
Red Hat Enterprise Linux (RHEL) 5.8, 5.9, 6.3, 6.4 (32/64-bit)
Oracle Enterprise Linux (OEL) 5.8, 5.9, 6.3, 6.4 (32/64-bit)
CentOS 5.8, 5.9, 6.3, 6.4 (32/64-bit)
Debian Wheezy (32/64-bit)
VSS support for Windows Server 2008R2 has been improved and reintroduced
Improvements to logging in Dom0: logs cannot over-consume Dom0 resource, increasing host stability
Live Storage Migration is now possible from the VM Storage tab in XenCenter
Support for additional CPUs (AMD Piledriver, Intel Haswell-DT)
Updated in-box device drivers
Minor Hypervisor upgrade (Xen-4.1.5)
Updated DM Multipath (0.4.9.56)
Support for alert severity filtering in XenCenter
Updated XenServer alert severity levels for consistency

A base é Centos 6 e depois incluí muitos outros projectos open source.
É pena a consola de gestão só funcionar em Windows (não sei se funciona com Wine), mas tendo o código cá fora, pode ser que apareçam versões ou outras consolas para outros sistemas operativos, ou de preferencia um consola web.
Assim, um dos maiores players na area de virtualização, lança um produto extremamente completo, free e open source. Provavelmente para não perder relevancia neste mercado competitivo.

* Na verdade, há uma funcionalidade que falta na versão open source. O updater gráfico via XenCenter, mas os updates podem ser instalado via consola, se bem percebo, com o yum.
