libvirt- Create virtual machine with text console only interface

virt-install is an amazing tool to create VMs. If you have created a config file (Kickstart file – ks.cfg), then its only one line un-attended install. If you are using this on remote host with ssh and unluckily cannot export display – what do you do. Do a non-graphical install. There are only minor changes in the command to tell the installer that there is no graphics available and it is amazing, is it not 🙂

virt-install --name test --os-variant=centos7 \
--description "CentOS 7.5 VM" --extra-args \
"ks=ks7.5.cfg console=ttyS0,115200n8 serial" --graphics none --console pty,target_type=serial \
--ram 60240  --vcpus 23 --disk path=/tmp/vm.qcow2,bus=virtio,size=20 \
--location /centos.iso --os-type=linux --hvm --accelerate \
--noautoconsole --wait=-1


Especifically for the no-graphical installation, I have added the following:

console=ttyS0,115200n8 serial — in extra-args

–graphics none

–console pty,target_type=serial


These options will enable installing the VM in a Text install mode and thus saving your day.

IT Trends That Will Boost Global Economic Growth

IT has been known to have a great impact on the global economy and has been linked to marketplace transformation, better standards of living, and international trade, among other things.

Here are some IT trends that are expected to further boost the economy in the near future.

IT Trends That Will Boost Economic Growth

Artificial Intelligence

This is the use of robots and artificial intelligence to carry out task previously done by humans. AI tech and its related technologies will help boost economic growth by creating many new jobs, increase production efficiency, reduce costs, and improve the quality of products.


5G is the next generation of mobile wireless network technology. It is believed that 5G will improve customer experiences and business utility via effective connectivity and faster data transmission.

5G stands as a change from previous generations of mobile technology. It enables lower latency, thereby reducing the time signals need to travel through the network. This makes it possible for it to support a wider range of applications, robotics, and the Internet-of-Things (IoT).

Blockchain Technology

The use of blockchain technology has grown steadily over the years. The healthcare sector is the major user, closely followed by financial institutions. Blockchain technology has a lot of untapped potentials, as it helps to improve transparency, reduce transaction costs, reduce frauds, increase overall operating efficiency, etc.

Three-Dimensional (3D) Printing

3D printing is rapidly changing the way we live and conduct businesses. 3D technology is already being used in several industries for a wide range of purposes. It will also be of great use in the healthcare sector, manufacturing industries, and so on.
