Docker’s popularity and usefulness in cloud systems architectures is evident, having won over countless developers. Yet, it’s not a replacement for mature, proven and security-hardened virtualization technologies that support many of the world’s largest clouds in production.
In this industry, everyone seems to talk about innovation, but very few platforms exist which foster innovation. More times than not, “innovation” is simply a buzzword used by some marketing campaign to hawk something about as novel as twenty-year-old accounting software.
Recently, with the release of a new 8.x version of Dell SrvAdmin tools, the Centos/RHEL5 (and XenServer, by the way) repositories disappeared. It appears that Dell will not support the RHEL5.x brands anymore.

This solves the problem for XenServer as well.
It all started with pvgrub2: it was March 2015 and I wanted to add grub2 to the Xen build system. We were already building grub-legacy as part of the Xen build, so that we could produce a pvgrub binary to be used to boot PV guests. After Vladimir ‘phcoder‘ Serbinenko’s good work on grub2, the latest and greatest upstream grub2 could be built with Xen support and used to boot PV guests. It made perfect sense to add grub2 to the Xen build system too, right? Maybe not.
When installing Oracle RAC (or in its more modern name – GI) version 18.104.22.168 and above, you can use Oracle ASM DiskGroup as your CRS+Voting file location.
It is fairly simple changing the disk membership in Oracle ASM DiskGroup, however, when you face some unknown bugs which prevent you from doing just that, or when you are required to modify the ASM DiskGroup on which the CRS+Voting files are placed, the article below is the one for you. You would have to remember, in addition, the ASM spfile.
ARM joined Xen Project two years ago as part of its drive into servers, networking and the emerging “Internet of Things” markets. In our latest “Future of Xen” video, Thomas Molgaard, Manager of Software Marketing – Systems & Software at ARM, talks about changes unfolding in enterprise and cloud computing that are creating new opportunities for his company and virtualization.
A few weeks ago, we introduced the Xen Project – OpenStack CI Loop, which is testing Nova commits against the Xen Project Hypervisor and Libvirt. Xen Project community is pleased to announce that we have moved from Quality Group C to B, as we’ve made significant progress in the last few weeks and the Xen Project CI loop is now voting on Nova commits.
