Enabling 64-bit Operating System's options in Oracle Virtualbox


While installing the guest OS on Virtualbox, if it doesn't show the option to choose 64-bit OSes like Ubuntu64 or RedHat64, you may perform below steps to enable 64-bit Virtualization :


Both Virtualization options like "Intel (R) Virtualization Technology" and "Intel (R) VT-d Feature" can be enabled at the hardware level in the BIOS utility.



1) Go to to BIOS Utility (Press F1/F2/F8/F9/F12 based on your settings while booting up system).

2) Go to Advanced Options

3) Go to Security Options

4) Set Virtualization Options to Enabled

5) Save, Exit and Reboot the system


That's it, now you can see the option to install 64-bit OS in Virtualbox !!

With such requirements, it has become imperative to build an application with robust APIs or Cloud Services having fault-tolerant and graceful fallback functionality. Spring framework has emerged as a full-fledged, robust, feature-rich and mature ecosystem over time. It has been equipped with lots of features for rapid development. Spring Boot dominates the Cloud Native Software development. With the introduction of Spring Boot, the Microservices development has catapulted to a whole new level as it brings all sorts of dependencies in one place. Spring Cloud is an umbrella project under the Spring ecosystem. It consists of many sub-projects to build a robust distributed system. It was primarily developed by Netflix and open-sourced as part of Netflix OSS to create resilient, fault-tolerant and s...

When I run it on a system with a fresh VS installation, it goes through the install process with no problems, but the components don't show up in the toolbox. When I try to register the asset as a Microsoft.VisualStudio.ToolboxControl, I get the error 'The target "PkgdefProjectOutputGroup" does not exist in the project.  To reslolve the below error which comes while adding reference of DLL application to VSIX project for Visual ...
