Test4Theory@home: Migrating Theory VMs to 64 bit

We are starting the migration from a 32bit to a 64bit VM for our Theory simulations. A beta application is available for volunteers to test - to participate, please check the box "Theory Simulations 64" (inside "Edit vLHCathome preferences"). You also need to accept test applications to get these tasks.

IMPORTANT: Hardware virtualization technology extensions (VT-x for Intel or AMD-V for AMD) need to be enabled in your host CPU as indicated on the http://lhcathome.web.cern.ch/join-us page. You can find more information here for Windows and Linux systems: http://www.sysprobs.com/disable-enab...echnology-bios. Mac systems are OK.

The "Show VM console" layout is simpler with the new VM - the hot keys used are:
ALT-F1: Boot console (only used while the VM boots)
ALT-F2: System information: top running processes, memory usage, etc.
ALT-F3: Job logging - combined scheduler, stdout, error logs (colour coded)

The "Show graphics" logs are also slightly modified.

Otherwise this new application is similar to the "Theory Simulations" application, but it uses the latest vboxwrapper version; 26178.

We have started drip-feeding new beta tasks with the Theory 64 bit application to validate the app. Then there will be more jobs coming next week.
