South Africa is a mystical country. Most people - especially North Americans - think we are a 3rd world country, people live in shacks and lions roam the dirt roads.
But alas - today I will prove them all wrong. Show me where in the WORLD you can find divine human beings such as these two mythical healers - right here in Sandton in Johannesburg. I will show you their resumes as I cannot even begin to express their awesomeness in my layman vocabulary.

That is... Almost 14 hours. Eish.
So you want to get your Linux physical machine running inside a virtual machine under Parallels Desktop for Mac? The straight forward way would be to use Parallels Transporter Agent on the Linux machine, however for me under Ubuntu 10.04.1 x64 it caused the machine to forever hang at the "Gathering information" screen... And if you kill the agent then Ubuntu hangs and refuses to restart. I clearly needed a different tactic.
What I did to get my Ubuntu Linux 10.04.1 x64 running happily inside my new Parallels Desktop for Mac 6.0, was the following:
On the source Linux machine, as root dump the whole hard disk (not a partition - the WHOLE disk)
dd if=/dev/sda of=/mnt/backup/192.168.0.1.hdd bs=65536
Obviously substitute /dev/sda for your primary hard drive you want to copy, and /mnt/backup/192.168.0.1.hdd for the destination file to be created. There needs to be sufficient free disk space on that target mount point to contain the source hard disk's capacity.
