This is an old question, but:
You won't be able to use KVM to run an x86 guest on the Raspberry Pi (any version), as the Raspberry Pi uses an ARM CPU core. Now, this doesn't mean that you can't run an x86 guest at all, but performance will be quite slow. (The link above is likely about using KVM to run an ARM guest, not an x86 guest).
Before the KVM ...
Depending on what performance is acceptable, plain QEMU without KVM may be a viable solution. Assuming you need to run x86 system installed in disk.img,
apt-get install qemu-system-x86
qemu-system-i386 -hda disk.img
This is enough to run old stuff (DOS, Windows 95 and their equivalents from the nineteens in other architectures).
Another virtualization ...
...from an image file that contains a simple plain-text file tree...
This is gobbledygook. You are confused. That is not what an operating system image file is. It is a binary, block-for-block duplication of either a single filesystem, or (as with the ones used for the Raspberry Pi), a block device containing multiple partitions and a boot sector.
It appears that VMware are working on a bare-metal hypervisor (ESXi) for 64-bit Arm processors, as they have showed off on their VMworld US shindig in Las Vegas (August 2018).
It seems that soon we will be able to cluster multiple Raspberry Pi 3 model B+ (arm64), into a normal working virtualization solutions as wee see today with x86.
You can run qemu-system (without KVM !) inside Virtualbox - this works fine across architectures.
The real problem is that the board emulation
"Versatile" can not run "Raspbery Pi" operating systems properly.
Build QEMU from source , it supports the "Raspberry Pi" board.
Xen definitely supports the ARM7/8, but they do not list the RPi in their supported hardware. There are lots of virtualization-related libraries in raspbian jessie, but they all seem to be about managing other platforms, not managing a hypervisor running on the Pi. It could be that the particular flavor of the ARM core used on the SoC is missing some ...
There is a simple way to access/configure your RPI directly on the laptop without screen and keyboard using ssh.
You can access your raspberry pi, you need to set its IP in the same subnetwork as your computer. For example, if your IP is 192.168.0.123, you set your rpi address to 192.168.0.X , X being between 2 and 254 and different from your computer IP.
On my Raspbian Jessie installation, the Kernel (4.4.27) is compiled with CONFIG_SECCOMP but not the filter option (CONFIG_SECCOMP_FILTER and CONFIG_HAVE_ARCH_SECCOMP_FILTER). So you will not be able to activate seccomp profiles on LXC (or Docker). See issue: https://github.com/raspberrypi/linux/issues/1172
In addition, there are no user namespace support ...
I succeeded in launching Raspbian Jessie Lite on Kubuntu 14.04 after I compiled QEMU from git. There's a bit of a problem though: I haven't made the keyboard input work (have to use virtual serial terminal instead).
Anyway, here's what I did:
1) Compile QEMU from git (adjust configure options for your needs, but these did work well enough for me):
$ sudo ...
Load Balancing is the distribution of work over a series of devices in a client server model. It's totally unrelated to what you're trying to accomplish.
A local cloud, aka fog computing is simply the management of a web application that runs on your local intranet. It is also completely unrelated to what you're trying to accomplish.
That being said, what ...
I added the following lines to my config.txt file in /boot.
# NOOBS Auto-generated Settings:
This forces the headless pi to 1080p. I've seen other similar posts but this is what is working for me.
That video is for installing on Windows. Windows uses .exe files as executables; other operating systems don't. Unix-like systems such as Linux and macOS don't generally use extensions in the same way as Windows does to indicate file type, and usually an executable has no extension at all in a Unix-like systems. The history of that is quite complex, but you ...
Realistically you can't, VirtualBox is for x86(-64) ISAs only, whereas Pi oriented images are ARM based.
You would have to take the source code for everything in the base image and recompile it -- which is not realistic.
You could take stock Debian and tweak it in the same ways as Raspbian does. There are probably a few things in ...
The Raspberry Pi has an ARM processor which is incompatible to the x86 processor family of your MS-Windows PC. That's why VirtualBox et al. do nothing.
You have to emulate the ARM processor in software. QEMU can do this, but it's rather slow. See e.g. here.
I hate to be the bearer of bad news, but you can't do what you propose (at least not in a practical way). Reason is that Raspbian is compiled to run on an ARM processor, and AFAIK, there are no laptops with ARM processors that also run an OS with support for VMs. In other words, a true Raspbian VM will only run on an ARM processor, and therefore won't run on ...
I would recommend you to have a look at Ansible as I am already using it to update some hundred Pis that are distributed over various places and sometimes also are only connected via LTE.
To reach all those Pis, I configured an openvpn-server to which all Pis connect when they boot.
In Ansible you can write playbooks and more or less you can do everything ...
Get Oracle Virtualbox (it's a free download from https://www.virtualbox.org/) get Debian Stretch X86 (32-bit) from https://www.raspberrypi.org/downloads/raspberry-pi-desktop/ and boot that in a Virtualbox.
One of the questions you linked actually does point to the answer: in Django 1.8, the patterns function became obsolete, and was replaced with a normal Python list.
The correct urls.py would be as follows:
from datetime import datetime
from django.conf.urls import url
from app.views import home, upload

IoT Core version 16299 has a known bug with the Remote Desktop Client on Raspberry Pi devices: https://docs.microsoft.com/en-us/windows/iot-core/release-notes/commercial/fallcreatorsupdate
According to LAmadio_MSFT in the comments on the page, a fix is in the works and should be released in the (near) future.
It seems the normal user can't delete items in /sys/fs/cgroup . You can try to add permissions or make that user owner on that folder recursively with chown yourUser /sys/fs/cgroup -R. Try that, if is not working "play" with chmod. Anyway, it looks as a permissions problem.
From the link you posted,
sudo systemctl enable vncserver-x11-serviced.service
This will enable the service to start when booted. It will not start the service though, you'll need to either start it or simply reboot your pi
Recent versions of QEMU aim to directly emulate the Raspberry Pi 1 , 2 and even 3 instead of "Versatile PB". You should especially keep an eye on QEMUs "user mode" emulation feature which sadly only works on Linux.
You can directly modify SD card images "from the inside" (apt-get etc.) this way !
To get an idea of the power of this approach in ...
This is not an answer to the question you asked, which is difficult if not impossible.
On the other hand if you do not wish to keep "dragging my mouse and keyboard and internet connection back and forth to the other room" this is easily solved.
Most distributions are easier to setup INITIALLY with a keyboard and mouse, but once this is done you can ...
This has to be possible I just don't know how.
Don't be so sure. The only emulator I'm aware of which is widely available for any model of Pi is QEMU, and while that definitely can be used to emulate the BCM 2835 based models (A/B/+/0), and there is some indication that it might be usable to emulate the BCM 2836 (i.e., the Pi 2), the status of the BCM 2837 ...
Given the similarity in kernels between the 2 and 3, this tutorial might provide some guidance.
The context is CentOS running on top of KVM, but the author has done a detailed job of describing the steps to getting the Pi ready for virtualization.
