======== Danube Cloud Community Edition 3.0.0-rc4 ======== Platform password: echaeJaif9phaiso Platform release: 20180318T095138Z (upstream/release-20180315) SHA1 checksum (esdc-ce-cn-3.0.0-rc4.img.gz): 5118014b7b97da2aeabf2c35611dfd833e35c954 === Release Notes === **NOTE**: When upgrading from 2.x, the software update **must** be performed manually [1]; first on the management server and then on all compute nodes. **NOTE**: This version relates to a new platform version. The platform image should be also updated [2]. It is **required** when you plan to use: KVM live migration, network overlays or want protection against the Meltdown attack [3]. **NOTE**: The 3.x compute node cannot be installed into a Danube Cloud deployment with a 2.x management virtual server. The management server [4] has to be updated first. ---- The Danube Cloud Team is pleased to announce the preview release of Danube Cloud version 3.0. The new major version of Danube Cloud includes plenty of new features. The most interesting one will be definitely the introduction of **Live Migration** for KVM virtual machines. The Live Migration capability in Danube Cloud does not depend on shared storage. The decision to implement this feature was mostly based on wishes and needs of our users. This feature should be considered experimental for now. Another important feature inspired by requirements of our customers are **Network Overlays [5]** and **VXLANs**. With this feature integrated into Danube Cloud it is much easier to interconnect compute nodes residing in various datacenters. It is now possible to control compute nodes in other physical locations connected via internet (without the need of a L2 connection). Virtual machines in different datacenters can see each other as if they were connected locally into the same local private switch. Version 3.0 also adds another major feature: Zabbix **Alert Management**. *Who* should receive alerts for *which* servers can be now configured via Danube Cloud. Listing of current and historical monitoring alerts is available from the Danube Cloud web management console. Besides many features and bug fixes, the official User Guide got also some interesting updates. Most notably there is now a **Disaster Recovery HOWTO [6]** and a new **Upgrading Guide [7]**. The 3.0 release includes a new system menu intended for Danube Cloud operators and the software update functionality was completely re-implemented. Therefore the upgrade from 2.x should be performed manually [1]. ---- [1]: https://docs.danubecloud.org/user-guide/maintenance/update.html#updating-danube-cloud-software-manually [2]: https://docs.danubecloud.org/user-guide/maintenance/update.html#updating-platform-image-on-compute-nodes [3]: https://meltdownattack.com/ [4]: https://docs.danubecloud.org/user-guide/install/admin-dc.html [5]: https://docs.danubecloud.org/user-guide/network/overlays.html [6]: https://docs.danubecloud.org/user-guide/howto/disaster-recovery.html [7]: https://docs.danubecloud.org/user-guide/maintenance/update.html
