CloudStack 4.0正式发布 云平台功能全面升级

 尽管还在孵化状态中，CloudStack 4.0发布证明了自己的价值，这是CloudStack贡献给Apache Software Foundation后发布的第一个版本。但这个版本并不代表CloudStack的成熟度或稳定性。在过去的6个月时间里，社区为今天的发布做了相当多的工作：增加新的功能，大量的Bug Fix，修复一些安全问题，完全的代码审查(包括代码自身及License兼容)等等。4.0版的更新如下：

Inter-VLAN Routing (VPC)

Site-to-Site VPN

Local Storage Support for Data Volumes

Virtual Resource Tagging

Secure Console Access on XenServer

Added the ability to create a VM without immediately starting it (via API)

Upload an Existing Volume to a Virtual Machine

Dedicated High-Availability Hosts

Support for Amazon Web Services API (formerly a separate package)

AWS API Extensions to include Tagging

Support for Nicira NVP (L2)

Ceph RBD Support for KVM

Support for Caringo as Secondary Storage

KVM Hypervisor support upgraded to work with Ubuntu 12.04 and RHEL 6.3
