CaeLinux emulated in qemu... was created by Alex
Hi Forum
I will have to give away my laptop for repair next week, so I am thinking on How to use my linux engineering apps like OpenFOAM in a windows coputer at university....
All those computers are win""##$...
so I was considering Installing caeLinux in portable emulation environmet... like qemu...
it is not difficult to do it...
My only issue is on How to save my work and port it to be accessible "outside" the caeLinux Image....
meaning port the OpenFOAM databases to my usb disk so that they be processed and accessed with thirdparty software...
... How to save my own OpenFOAM solvers within CaeLinux image... is it even possible...?
Best regards
Alex

Hi Alex,
personnally, I had the same issue while developing CAELinux. The solution that I found is to install CAELinux in a virtual machine (I recommend you VirtualBox or VMWare instead of QEMU) on a USB 2.5" harddisk. I did allocate a rather large space to the virtual disk (something like 20Gb) and allocated 1Gb of RAM. The OS was installed very simply by mounting the ISO as a virtual DVDRom and booting the virtual machine.
Then I have installed VMWare player (it may be better to use VirtualBox though... it is a more openSource...) on all my guest machines so I can run my "virtualized" CAELinux everywhere. As it is a real installation of the OS on a harddisk, all the changes are permanent and thus you can keep your files, modify the codes and so on. To transfer the files to the "outside", just create a shared folder on windows and browse the network in the virtualized CAELinux to drop the files in there. This is usually a relativelly trivial task.
I hope that it will help you to have your perfect environment !!

Hi Joel,
Just one thing, when I spoke about qemu, i was concerned about the issue of speed of emulation...
As you surely know... some apps in caeLinux are very numeric-intensive... so, speed of emulation becomes the bottleneck of my implementation...
... based on Your experience, which would you advise to be the fastest emulator... qemu, vmware or virtualBox...?

Hi,
concerning speed, I have not measured it..,but from my experiments, it seems that VirtualBox and VMWare are significantly faster than Qemu. The most stricking change is on the responsiveness of the graphical interface and disk access. I have not benchmarked this, but I am sure that CPU is also faster in VMWare or VirtualBox than Qemu.
To try that, I recommend you to either download CAELinux VMWare version (=> you will only need VMWare player or the latest VirtualBOX to run it) or install it manually (I recommend VirtualBox in this case, as it is FREE).
CAELinux is based on a now rather old release of PCLinuxOs 2007 which means KDE3.5..
