KVM? Us? Amazon erases new hypervisor from AWS EC2 FAQ

Amazon Web Services has quietly edited its FAQ in which it revealed it has created a new KVM-based hypervisor and will use it instead of Xen for future instances. The webpage now contains no mention of the hypervisor. But Google's cached record of the page does. And in case AWS manages to get that scrubbed, we grabbed this …

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 …

How much do containers thrash VMs in power usage? Thiiiis much

Ericsson researcher Roberto Morabito has compared the power consumption requirements of virtual machines and containers, and found the latter more economical. Power Consumption of Virtualization Technologies: an Empirical Investigation put Xen, KVM, Docker and LXC through their paces on a series of tasks and measured how many …

Nutanix did build 'Acropolis' hypervisor, wants you to bury it

As predicted by The Register, Nutanix has built a hypervisor called Acropolis, but is using it for more than scale-out compute and an assault on VMware. Instead, the company wants to abstract all the stuff that makes up modern applications and make managing infrastructure idiot-proof. We'll explain that in a moment. The …

SimpliVity opens its doors to KVM, OpenStack

Hyper-converged infrastructure company SimpliVity has announced it now supports the KVM hypervisor and OpenStack. SimpliVity's schtick is that everything below the hypervisor – especially data compression and de-duplication for back-up, networking and cloud-tiering storage – should be handled by a hyper-converged appliance. It …

If hypervisor is commodity, why is VMware still on top?

The hypervisor is a commodity. VMware's ESXi, Microsoft's Hyper-V and the open-source community's Xen and KVM are all right and proper tools for virtualising workloads. Does that mean we should all stampede away from expensive proprietary hypervisors and dine on the open-source freebies? This being IT, the answer is "it depends …

Nutanix looking for a way to burst VMware's bubble

Comment Rumours are circulating about a hypervisor built by Nutanix, and Nutanix open-sourcing its software; two intriguing moves. Why would Nutanix make these moves as VMware ratchets up its attack on hyper-converged vendors with EVO:RAIL? Start-up Nutanix is a hyper-converged infrastructure appliance (HCIA) supplier, widely-regarded …

Docker kicks KVM's butt in IBM tests

IBM Research has run done a side-by-side comparison of the KVM hypervisor and containerisation enfant terrible Docker and found the latter “ equals or exceeds KVM performance in every case we tested.” Big Blue tested the two using the linear-equation solving package Linpack, the STREAM benchmark of memory bandwidth, network …
