The security threats we’re facing today are becoming increasingly sophisticated. Rootkits, and malware taking advantage of kernel and 0-day vulnerabilities pose especially serious challenges for classic anti-malware solutions, due to the latter’s lack of isolation: they’re typically executing in the same context as the malware they’re trying to prevent.
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 126.96.36.199 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.
