so whats the feedback on the VM? 🙂 like it, makes your life much easier, too complicated…? what should we improve…? ---

I think the newer VM goes a little bit smoother than the previous version. The directory structures are fairly self explanatory and the steps are easy to follow. Doing it a few times, I now know the “architecture” of it and am playing with creating apps. Now I ran the “make” file only. Looks like it built update files for each WP module and for the red and green board. I think I could have done a make red\_wp85 and it would have only built for my particular board and module. Looking at my older VM, I do see that it only built for the red wp85, so I guess I could have saved some build time just building for that. Lastly with both VM’s, I have had some issues with computer resources. I guess the default settings is for the VM to use 3.5GB of RAM. My computer only has 4 GB of RAM total, so sometimes it will freeze up. But I have lowered that down to 1.5 and will see how it does. I have a dedicated desktop computer for mangOH Red development. ---

I’m lowering the default RAM to 2 GB based on the fact that I didn’t see any difference in compile time when building using the command line. It may be necessary for dev studio users to bump up the RAM allocation. I haven’t really explored that though. ---

might also consider vm images for KVM too, as its much more efficient then virtualBox… which requires being installed, where kvm has a much cleaner integration with linux and tools like virt-viewer and libvirt you could probably export you vb image as raw and just post it also to the forum, again note a ton of people use vmware also, having only one choice makes it more difficult for users and forces them to a specific tool, other hands is … more Vms to create manage and support ---

I have only used the mangOH VM under virtualbox so far. I believe @nick is using vmware to run the VM. He told me that virtualbox didn’t work well for him on Mac OSX. I agree that kvm would be better/faster/etc for running the VM on Linux. A little bit of searching indicates that it’s possible to [convert a .ova file to be used with KVM](https://wiki.hackzine.org/sysadmin/kvm-import-ova.html). If you’re already running Linux though, I feel like a docker container for the build tools and build dependencies would be more useful than a full-blown VM. I know the Developer Studio team did some work on docker toolchains, but I think they were only focused on building Legato apps and not on building the Legato framework itself or building the yocto based Legato Linux image. ---

We’re definitely considering trying something Docker based such that we can build in the cloud easily. We don’t have any solid physical build servers yet so it may be a more suitable solution. VMware was more of a quick fix since it worked better than VirtualBox. ---

We’ll try it out. Could you send the link to download? thanks. ---

Hello Asyal I have tested your new VM. Very great Job ! Francis ---

Hello, In case someone is interested: I wanted to start trying to understand how mangOH Red development environment is structured and works. So I decided to create my own VM, from scratch. I used Linux Mint, as I’m not a big fan of Ubuntu window manager. It seems that I partly reached my goal: I was able to rebuild mangOH platform, and update the board 🙂. I now have to create my first application… You’ll find the steps I followed described [here](http://systev.com/mangoh-red-using-a-linux-mint-vm-for-development/). Disclaimers: - I’m still a beginner in the world of mangOH, so do not consider my article as expert’s advice - I would recommend that you stick to the official VM, unless you want to do what I started to do: trying to understand the ins ou outs of mangOH development environment ---

Just added Developer Studio to the VM. Steps described [here](http://systev.com/mangoh-red-configuring-developer-studio/). ---

Thanks for writing that article @pascalb! I’m updating the mangOH VM right now to use Ubuntu 18.04 which includes Gnome 3 rather than Unity so people might notice a few visual changes if they download the new VM. [Previous page](https://mangoh.discourse.group/t/mangoh-vm-feedback/1230.md?page=1)
