SYSTEMS LEVEL CONCEPTS

A hypervisor is a software which is installed on top of the hardware, creating a virtualización layer and acting as a platform on which virtual machines (VMs) are created. Do not confuse the hypervisor with the operating system in question.

The hypervisor is responsible for extracting physical resources from hardware and converting them to virtual hardware. It is key to facilitating virtualization, creating what is known as the virtualization layer.

The same way as you must install the software to use the hardware, the hypervisor must be installed to allow virtualization.

Now that you know that virtualization hosts (hypervisors) provide hardware the ability to virtualize and therefore create multiple virtual machines running on the operating system (OS) of your choice whose function is partitioning.

The definition of partition in this context is the ability to execute multiple operating systems on a single physical system sharing the underlying hardware resources.

In a virtualized system, the hypervisor partitions, that is to say, It divides the hardware into several 'parts' to allow multiple OS running on a single machine.

The wiring day (Raul Garcia)

This wednesday we had an special class. Instead of having or usual AWS lections, we had to make lots of Ethernet cables, wich, might sound boring, but sure it wasnt. We started slow, there was more than 2 hours left, and the recess was just around the corner, we only had to make 28 wires, which had to be more than 5 meters long. Only a few cables were made when the recess started, when we came back we kept going with our chore Every single wire had to be made with caution, just a small mistake and all the process had to be started again, which made the work quite stressful. Luckly I didnt make any mistake, and managed to make 4 cables. The last hour of the work was the worst, only then was when we realiced how many of them were missing, so all of us, tired and stressed started to make as many as possible to reach the goal. At the end all of the class managed to make 25 in total, which wasnt 28, but close enough to be ok. At least for me it was a really fun experience, and we will have
