From someone in my Meetup group so thanks to him for this:
I am adding 64 Bit Ubuntu to my laptop under Oracle Virtual Box. Here is a tip that may help your group. In order to install 64 Bit version of Ubuntu in Virtual Box I needed to change my bios setting to Virtual Technology Enabled . I also am updating my bios and drivers. You may have covered this already, but I thought it could not hurt to repeat this.
This came from an ‘insider’ to set up a remote server for live trading:
GovReady™ CentOS 6.5 x86_64 pre-hardened FISMA “server” profile. OpenSCAP, SSG, GovReady installed.
[11:52:40 AM] : http://www.vagrantbox.es/
[11:52:45 AM] : government standard hardening
[11:53:25 AM] : theres also some open source tools out there
[11:53:32 AM] : where you can just install your server with all the things you want on it
[11:53:36 AM] : run a scanner
[11:53:42 AM] : and it will tell you where you might have holes
[11:53:48 AM] : and things to fix with the commands to run to fix them
[11:53:51 AM] : make sense?
[11:54:12 AM] : u don’t have to bring it on a network access
[11:54:18 AM] : before scanning too
Cool. Thanks to him for sending. This will make life much easier
‘ve got the solution! I created a complete new VM for rhel6 and made a base installation. The new vm was running very well so I compared the settings from my very slow vm created along time ago with VB 3 and noticed that on the newly created vm under VB 4 “Enable IO APIC” (System –> Motherboard –> Extended Features) was selected. I selected it too and surprise surprise, the vm runs as expected!
How to set up a C++ Beowulf cluster for Open MPI for Rinside with VirtualBox and Ubunutu Linux
It looks like to implement the RInside C++ call into the FastFlow will not be fun. As a result, I am revisiting OpenMPI as RInside’s sample code already includes a sample with it implemented. I now focus how build how to build a virtual home network Beowulf cluster with VirtualBox:
1. Set each virtual machine with Ubuntu Server slave nodes and a Ubuntu Desktop for your master node.
