We need the computer (desktop, laptop or server) to have a CPU with (minimum) two physical cores. Please, keep in mind that the VM is just a computer without the real hardware.
On the other side, we must allocate sufficient resources to the VM. On one side, we must spare resources and limit their usage with the every single VM. Instead of that, all VMs are using same simulated hardware presented for them by the virtualization software. We just do not have separate hardware from some specific manufacturer. In the other hand, the VM is very similar to the physical computer. The resources on any physical computer (desktop, laptop or even server) are limited. Whenever we need to use a large number of the VMs, we need to put a higher load on the physical machine itself.
I decided after the presentation to discover where the problem lies. I made many VMs to simulate a very complex scenario I used different platforms and operating systems, like Mikrotik RouterOS, Tiny Core Linux and the different Windows platforms. One of the virtual machines booted very slowly and this had some impact on the presentation. I mention this presentation because the demo part is important for today’s though. I will write about Mikrotik IPSec services in some another post. Rather than repeat the presentation, I decided to combine the slides and live demonstration. The Mikrotik User Meeting or MUM Serbia 2016 was only a few days ago, during which I delivered a presentation related to the Mikrotik IPSec services.
