Raspberry Pi Official Case

VDI comes to the Raspberry Pi

The Raspberry Pi is now a threat to thin clients. Citrix has been fooling around with the Pi as a desktop virtualisation (VDI) target for a while, even releasing a prototype Citrix Receiver for the little computers. That effort was in early 2014. Citrix has since decided it was inefficient to put a lot of effort into creating …

Hyper-V sets VM created date to 1601, in the reign of Good Queen Bess

Virtualisation mavens have been reminded that Microsoft’s Hyper-V has a bug that occasionally resets the “created” date of virtual machines to the year 1601. That's 1601 as in during the reign of Queen Elizabeth the first. Which we feel compelled to point out was quite a few years before the server was invented. The bug's …

Hypervisor headaches: Hosts hosed by x86 exception bugs

Various hypervisors and operating systems are scrambling to patch around an x86 bug that lets an admin-level guest crash the underlying CPU, causing a denial-of-service to anyone else on the same machine. The issue, described here, is that with some x86 CPUs, an attacker with kernel-mode code execution privileges on a guest …

VMware ponders VDI teleporting with swipe-between-devices patent

When Windows 10 makes it to mobile devices, one of the more interesting features will be “Continuum”, a tool that will make it possible to plug a phone into a keyboard and monitor and use it as a PC. You can already run a desktop OS on a mobile device, of course, through desktop virtualisation (VDI) software. But VDI tends to …

Citrix's boutique virtualisation strategy is working. Mostly

Citrix has taken the unusual step of releasing some market share data that doesn't show it in a completely flattering light. Citrix more or less backed out of the mainstream server virtualisation market in 2013 and 2014. In the latter year analyst firm Gartner said the company “is no longer investing strictly to keep up with …

Dell's VMware-as-cell sell isn't going swell

VMware yesterday posted a pretty set of numbers. And today its share price fell by twenty per cent, from Tuesday's US$68.97 to a Wednesday close of $55.38 after grazing $52.91. The reason for the dip is widely held to be remarks during its earnings call about the secular move to cloud representing a wave that even VMware will …

Now we do have cloud, and private …
