This can be avoided [...]
In my laptop I have a solid state disk, and frankly I am way past addicted to solid state disks, but what you get in performance you lose in capacity. As such I have had to be creative with how I can have the capacity and the performance that I need. Lately the solution has [...]

When you run into this a quick fdisk -l will reveal that you will need a new way to partition your disks. Fdisk will produce output similar to this… Use Parted to Create a Partition [...]

Now the big flaw with my first article was that by using dd on the hypervisor level, [...]
