we are trying to run our app that integrates jsbrowser on Raspbian 4.4.50-v7+ (raspberry pi 3) and get the message that the operating system is not installed.
we integrated the linux 32 and 64 bit libraries.
how to get jxbrowser running on Raspbian ?
The Raspberry Pi is an ARM-based platform. According to JxBrowser system requirements this platform is not supported at the moment by the JxBrowser library.

When I try to install HAXM I get the error:
This computer does not support Intel Virtualization Technology (VT-x) or it is being exclusively used by Hyper-V. HAXM cannot be installed. Please ensure Hyper-V is disabled in Windows Features, or refer to the Intel HAXM documentation for more information.
But in Windows Features Hyper-V is disabled: hyper-v disabled in features
In my system info, I have "Hyper-V - Virtualization Enabled in Firmware" as "No"; does has something to do with the problem?: hyper-v system info
My processor is an AMD, can I even have HAXM in and AMD pc?
If not, what can I do to run an Android emulator? (With Android Studio).
https://developer.android.com/studio/
Requirements and recommendations
The Android Emulator has additional requirements beyond the basic system requirements for Android Studio, which are described below:
SDK Tools 26.1.1 or higher
64-bit processor
Windows: CPU with UG (unrestricted guest) support
HAXM 6.2.1 or later (HAXM 7.2.0 or later recommended)
The use of hardware acceleration has additional requirements on Windows and Linux:
Intel processor on Windows or Linux: Intel processor with support for Intel VT-x, Intel EM64T (Intel 64), and Execute Disable (XD) Bit functionality
AMD processor on Linux: AMD processor with support for AMD Virtualization (AMD-V) and Supplemental Streaming SIMD Extensions 3 (SSSE3)
AMD processor on Windows: Android Studio 3.2 or higher and Windows 10 April 2018 release or higher for Windows Hypervisor Platform (WHPX) functionality
To work with Android 8.1 (API level 27) and higher system images, an attached webcam must have the capability to capture 720p frames.
I have a USB host C++ app running on Windows 10 that communicates by USB2 with an embedded USB device.
Now need to port to UWP C++ app on Windows IoT on Raspberry PI.
On my Windows 10, I first install the libusb-Win32 host driver into Windows.
Can't find how to do it in Windows IoT on Raspberry PI.
There is no out of box driver of libusb for Windows IoT Core, ARM, but you can build from source to target ARM architecture.
Source on GitHub.
If possible use modern USB API is easier.
Ref: "How to connect to a USB device (UWP app)".
I have made an OS is cosmos, but I cant seem to get the Raspberry Pi to actually boot the OS up. I made a bootable SD card and USB stick but the raspberry pi doesn't load anything up.
Cosmos os only supports the x86 processor type. All versions of the raspberry pi either use ARM_6 or ARM_7. A completely different type. So what I'm saying is Cosmos OS won't work on your raspberry pi because it was made for computers with a different type of computer chip. For your raspberry pi I suggest you use raspian which is the operating system the Raspberry Pi Foundation suggests using. You can download it here.
I have a desktop application (built with NW.js and the node-webkit-builder) that runs smoothly on Windows and OS X, however, I can't seem to open the executable on the Raspberry Pi. The NW.js builder outputs the 32- and 64-bit Linux distributions, as well, that I assume should operate on Raspbian or Ubuntu MATE. However, I keep getting the error:
cannot open the application since there isn't a readable executable.
Even after chmod +x the application, it doesn't work.
raspberry pi use arm architecture, you may checkout this: https://github.com/toxygen/armhf-node-webkit
Rasp Pis are using ARM processors and not the x32 and x64 processors the NW.js binaries support.
You will need to download a prebuilt for the ARM or build it yourself.
Here is a link to a prebuilt for 0.12.0. You will package your app just like you would on a x32/x64 machine.
Unfortunately ARM is still not an officially supported platform and if you wish to have prebuilts you will have to depend on community members/contributors.
You need the binary port of NW.js (node-webkit) for Raspberry Pi.
I have just created a repository with the node-webkit binary port that runs on Raspbian, tested and working on Raspberry Pi 1 and Raspberry Pi 3 so it is ARMv6 and ARMv7 compatible.
Here you can check it: https://github.com/jalbam/nwjs_rpi
to run the emulator in the new Android Develop Studio, I need to turn on the virtualization support (VT-x) on my guest windows 7 running in KVM, which in turn is on RHEL6.
Google shows we need vmx & vme in the guest processor definition, which I have them as 'require' from dumpxml. But in Android Develop Studio in my guest win7, it still complains about missing virtualization support.
Cannot launch AVD in emulator.
Output:
emulator: ERROR: x86 emulation currently requires hardware acceleration!
Please ensure Intel HAXM is properly installed and usable.
CPU acceleration status: HAX kernel module is not installed!
I then download 'haxm-windows_r05' and run 'intelhaxm.exe' to install it, with error:
VT not supported
This computer does not support Intel Virtualization Technology (VT-x). HAXM cannot be installed.
Please refer to the Intel HAXM documentation for more information.
In summary, my guest (windows 7) on KVM (running on RHEL 6) can not turn on Intel Virtualization Technology (VT-x).
Thanks for any help

Unfortunately, RHEL6 lacks support for Nested Virtualization. RHEL7 does but it's still very premature and new changes keep getting added. Your best bet is to install the current upstream kernel. To enable Nested Virtualization, load kvm_intel with "modprobe kvm_intel nested=1".
And ofcourse, you need to advertise vmx in your cpu definition.
