vSphere unsupported CPU

Posted Leave a commentPosted in ESX, VMware

So today I wanted to install vSphere 6.7 on one of my older machines. I needed some additional space to move a few VM’s to. So I downloaded the 6.7 ISO, created by bootable usb and plugged it in.

Posted Leave a commentPosted in Linux, Operating systems

Redundancy is very important these days, specially for a highly used medium such as mail. Luckily you can set up something as a “backup MX”.
