Why GlobalLogic Uses Xen (Overheard at CES)

We were lucky to have the opportunity to meet up with GlobalLogic at CES and talk to them about their Nautilus platform for automotive virtualization. A few years ago, no one understood why the company was demoing hypervisor technology as a part of Nautilus, a set of solution accelerators that includes architectural concepts, a modified […]

XENSERVER产品DUNDEE预览版2发布

2015 刚刚结束, 2016新年开始,正是我们向XenServer社区发节日礼物的好时节。我们发布了下一代XenServer产品Dundee预览版2。我们花了大量精力解决已上报的各种问题,也导致该测试版本和九月份的预览版1相比有些延迟。我们确信该预览版和Steve Wilson博客 (https://www.citrix.com/blogs/2015/12/14/citrix-xenserver-infrastructure-strategy/) 中对思杰在XenServer项目贡献的肯定是很好的新年礼物。此外,我们已开始在xenserver.org网站提供一系列博客把主要改进点做深度介绍。对于那些更关注该预览版亮点的朋友,现在就让我在下面为您做一一介绍。 异构处理器集群 多年来XenServer一直支持用不同代的CPU创建处理器资源池,但是几年前采用因特尔CPU发生一些改变,这影响了混合使用最新的CPU和相对较老的CPU的能力。好消息是,使用Dundee预览版2,这种状况得到了彻底解决,且确确实实提高了性能。这个领域需要我们把事情完完全全的做正确,我们非常感激任何人运行Dundee体验该特性并上报成功或者上报遇到的问题。 增强的扩展性 当代的服务器致力于增强其能力,我们不仅要与时俱进,更要确保用户能创建真正反应物理服务器能力的虚拟机。Dundee预览版2 目前支持512个物理CPU(pCPU),可创建高达1.5TB内存的用户虚拟机。您也许会问是否考虑增加虚拟CPU上限,我们已经把上限扩大到32个。在Xen项目的管理程序中,我们已经默认支持PML(Page Modification Logging)。 对PML设计的详细信息已经发布在Xen项目归档中等待审核。最后,XenServer的Dom0内核版本已经升级到3.10.93。 支持新的SUSE版本 SUSE为其企业服务器版SLES(SUSE Linux Enterprise Server)和企业桌面版SLED(SUSE Linux Enterprise Desktop)发布了version 12 SP1,这两者在Dundee中都已得到支持。 安全更新 自从Dundee预览版1在九月下旬发布后,若干安全相关的热补丁已经在XenServer 6.5 SP1中发布。 同样的补丁也应用到了Dundee并且已经包含在预览版2中。 下载信息 您可以在预览页(http://xenserver.org/preview) 下载Dundee预览版2,任何发现的问题都欢迎上报到我们的故障库(https://bugs.xenserver.org)。Read More
