Redhat is closely working with Intel and AMD to mitigate the risk of micro-architectural (hardware) implementation issues which are named as Meltdown and Spectre. These vulnerabilities are mostly affecting many modern microprocessors which include Intel, AMD, IBM power and ARM processors. These issues can be overcome by updating Linux kernel, virtualization-related components, and/or in combination with […]
Vulnerabilities – How to Fix Meltdown and Spectre on VMware vSphere ?
VMware vSphere also affected by multiple vulnerabilities since its uses Intel/AMD platforms. VMware vSphere has multiple layers of virtualization and sadly, you should apply/update the patches for all the components which includes Operating systems, virtual machines, virtual appliances, hypervisors, server firmware, and CPU microcode. Operating system patches can reduce the risk with help of hypervisor patches without […]
Meltdown and Spectre Vulnerabilities – Big Threats
Meltdown and Spectre Vulnerabilities have made 80% of servers as Vulnerable in overnight, thanks to Google Project Zero team and other security researchers who have brought such a worst vulnerabilities to the world (At least now). Meltdown vulnerability basically melts security boundaries which are normally enforced by the hardware (CPU). Spectre name is based on the root cause, “speculative […]

Virtual Machine Live Migration – How it works ?
Virtualization’s revolution has pushed many technical challenges from “impossible” category to the “possible” category. Live Guest OS Migration can be considered as one of the major benefits of the OS virtualization. Migrating the virtual machine from one host to another host without downtime facilitates fault management, load-balancing, and low-level system maintenance. It has eliminated all difficulties faced […]
Para virtualization vs Full virtualization vs Hardware assisted Virtualization
Virtualization is nothing but abstracting operating system, application, storage or network away from the true underlying hardware or software. It creates the illusion of physical hardware to achieve the goal of operating system isolation. In last decade, data centers were occupied by a large number of physical servers, network switches, storage devices. It consumed a lot of […]
