Virtualizing Haiku in QtQEMU

Virtual instances of operating systems are perfect for all kinds of testing purposes that need to be done in a safe and isolated environment. Installing Haiku in a virtual machine is a solution for people who do not want to install it on their physical computers, but wish to become familiar with it. This guide will describe the process of running Haiku in a virtual machine (VM) using QEMU 4.1.0 and an .

Emulating Haiku on DigitalOcean

DigitalOcean is one of the most popular KVM Cloud providers that allow the end user to upload raw disk images. As they don’t allow booting from ISO, we will need to use VirtualBox or other virtualization software for installing Haiku. This guide assumes that you already have a DigitalOcean account, you’re at least partly familiar with the interface and that you have already installed Haiku in a VM. You will need to obtain a disk image (*.

Ideas

For information about Haiku's participation in GSoC this year, please see this page. Qualifying students can apply for a Haiku project (see the list of suggested projects below). For details about how to apply, please check out Students: How to Apply for a Haiku Idea. The most successful Google Summer of Code projects are often those proposed by the students themselves. The following list represents some of our ideas and wishes for the project.

Setting up Haiku in Vultr

Vultr allows one to upload a custom iso on their instances. With this, many new possibilities are open - such as setting up a buildbot, automated testing, benchmarking and more. This task assumes you have a Vultr account and that you are aware that it will charge you for setting up and running an instance. Preparing a direct ISO link Vultr doesn’t allow one to upload a custom iso from a local machine.

Emulating Haiku in KVM

For Google Code-In 2019, Vrondir created a video on how to install Haiku in KVM [79 MiB]. Virtual instances of operating systems are perfect for all kinds of testing purposes that need to be done in a safe and isolated environment. Therefore, installing Haiku in a virtual machine is an ideal solution for people who do not want to install it on their physical computers but want to become familiar with it.

Emulating Haiku In ESXi

In 2017, Max Levchuk created a tutorial video for VMware ESXi [5 MiB]. Virtualizing an operating system might be a good way to give it a test run, or to use it alongside your main OS. ESXi is a platform that allows easy deployment of virtual machines on baremetal servers, and setting up a Haiku ESXi VM might be a good idea if you intend to develop Haiku or applications for it.

Accelerant

4. Accelerant As opposed to the kernel driver, the accelerant runs in user space. The accelerant provides functions that are needed to control a graphics card. These functions are used by the app_server and/or applications directly. There are a number of reasons for the graphicsdriver being divided into a kernel- and userspace part: Speed: When controlling the graphics card configuration (so programming the ‘registers’) is done using memory mapped I/O this can be done using pointers.

Flags

5 - Flags <td width="40%" valign="top"> <b>Chart Legend</b> <ul> <li><b>Name</b> - The name as defined in the BeOS header files.</li> <li><b>API Construct</b> - The construct used in classes and functions.</li> <li><b>C</b> - The command, from API of appserver or accelerant.</li> <li><b>S</b> - Status, from accelerant to API.</li> <li><b>P</b> - The app_server is target.</li> <li><b>A</b> - The accelerant is source or target.</li> </ul> </td> A flag is basically a single tray.

Conclusion

7 - Conclusion Writing video drivers is nice to do a while. It is very instructive and (yet) good to do when the whole structure is addressed. Sometimes writing video drivers requires the necessary imagination from the programmer, because it is difficult to test some (combinations) of things or make them testable. Also, the retrieval and understanding of the specifications is sometimes a challenge. Even if there is some documentation from a chip or card manufacturer, you still need to be puzzled regularly.
