Yesterday, all my VMs seemed so far away

A few days ago I had some exciting projects and I wanted to share those stories with you. However, I already finished them on the production machines and I decided to simply reproduce the whole process in my virtual lab.

I opened VirtualBox and I began to turn on all needful VMs. One machine started, then another one, everything looked fine as usual. Then my fan became very noisy, CPU load jumped on all cores and every other machine either endlessly booted or the boot process lasted almost 15 minutes.

The party just started! I took a deep breath and boldly went where no one had gone before.

Compress a virtual hard disk to recover valuable space

My laptops are equipped with SSD drives and those drives are very small comparing with commonly used hard disks. Additionally, that means that I have less space for my virtual machines. However, using SSD to store virtual disks will result in the high performance virtualisation. Power never comes free.
