HelenOS is a portable microkernel-based multiserver operating system designed and implemented from scratch. It decomposes key operating system functionality such as file systems, networking, device drivers and graphical user interface into a collection of fine-grained user space components that interact with each other via message passing. A failure or crash of one component does not directly harm others. HelenOS is therefore flexible, modular, extensible, fault tolerant and easy to understand.
We use newest available version to run:

Install Zabbix 3.4.1 on Oracle Linux 7.4 64-bit with Selinux enabled

Zabbix 3.4.1 on Oracle Linux 7.4 64-bit with Selinux enabled.
We will install Zabbix 3.4.1 on Oracle Linux 7.4 64-bit.

OS: Oracle Linux 7.4 64-bit
We install OS using VMware Workstation 12 Player. We use 20 GB partition with option automatic LVM.
After install make network interface start on boot
grep ONBOOT /etc/sysconfig/network-scripts/ifcfg-ens33 ONBOOT=yes
-set hostname:
hostnamectl set-hostname zabbix01 - do system update:
yum clean all; rm –fr /var/cache/yum; yum update –y Optional allow rule for ssh with firwall-cmd and install necessary packages: firewall-cmd --permanent --add-port=22/tcpyum install vim mc wget tcpdump -y
Finally after reboot we have newest possible kernel installed:
uname –aLinux zabbix01 4.1.12-103.3.8.el7uek.x86_64 #2 SMP Mon Aug 21 17:27:54 PDT 2017 x86_64 x86_64 x86_64 GNU/Linux
Next install your favorite X-System – for example:
yum groupinstall "X Window System" yum install gnome-classic-session gnome-terminal nautilus-open-terminal control-center l…


Visopsys  is an alternative operating system for PC compatible computers.  In development since 1997, this system is small, fast, and open source.  It features a simple but functional graphical interface, pre-emptive multitasking,  and virtual memory. 



SkyOS (Sky Operating System) is a discontinued prototype commercial, proprietary,  graphical desktop operating system written for the x86computer architecture
We download SkyOS from
Then we make virtual machine using iso downloaded with 2GB RAM.

As a former open source project, SkyOS has been the subject of many debates involving free software.


is an open source operating system currently in development. Specifically targeting personal computing, Haiku is a fast, efficient, simple to use, easy to learn, and yet very powerful system for computer users of all levels. Additionally, Haiku offers something over other open source platforms which is quite unique: The project consists of a single team writing everything from the kernel, drivers, userland services, tool kit, and graphics stack to the included desktop applications and preflets.

We use haiku-nightly-anyboot iso to prepare Virtual Machine.

After install reboot machine.

If You want to install some packages or update system just use pkgman :)


Redox is a Unix-like microkernel operating system written in the programming language Rust, a language with focus on safety and high performance.
Redox is inspired by previous kernels and operating systems, such as Minix or BSD.
The Redox OS Kernel is a hybrid kernel that supports X86_64 systems and provides Unix-like syscalls for primarily Rust applications.
The website can be found at
After download iso file we can start Virtual Machine with Redox:

Have a fun ☺
