Iam going to build this based on a series of small posts I've made as I feel much of the information is actually hard to find and piece together from the rest of the web.
What I'm going to focus on is how to use virtio as the NIC because if you don't you get very slow NIC speeds but with the virtio NIC model you basically get host speeds.

On a test machine Iwas never able to access to a newly created 4th partiton. As we can see there are dev devices for everything but the 4th partition.
The normal "partprobe" or "kpartx" or kernel being told to rescan the block device didn't help (only a reboot did).
fdisk -l /dev/sda
Disk /dev/sda: 750.2 GB, 750156374016 bytes
255 heads, 63 sectors/track, 91201 cylinders
The old MBR 512 bytes partition table is no longer valid if you are using GPT.
To copy a GPT table with dd to another disk do it like so:
Below sda is the source disk and destination disk is sdb (change to meet your needs).
dd if=/dev/sda of=/dev/sdb bs=1536 count=1
You can also use dd to backup your partition table like normal but with the bs of 1536
1.) Replicate the number of partitions in your new drives.
I created 3 partitions of the same same size.
partition #1: +1G (/boot)
partition #2: +60G (swap)
partition #3: rest of it (/)
#note if you are using GPT/gdisk you need to create separate a partition at least 1MB in size (in my case I would a 4th partition and mark it type ef02).........
sudo fdisk /dev/sdh

But if you do:
it does work, I think hd0/sda had a GPT partition that was not removed properly (what I did was just dd bs=512 count=1 the partition table from another drive since the partition table should be identical).

fdisk unfortunately can't do this and I'm not sure if there's any updated version that handles it but parted can do it.
Here's an example of how to do it:
parted /dev/sda print
1 17.4kB 1024MB 1024MB ntfs primary
2 1024MB 16144MB 15120MB ntfs primary
/dev/sda1 would be the first partiton
/dev/sda2 would be the second partition
You can then just access them like any other normal partition.........
At first it was configured as a RAID 0, then I deleted the Virtual Disk Group.
I thought both drives would be shown and detected in Linux as sda and sdb but it actually shows nothing.
To make them work you have to hit Ctrl+R before the system boots (when prompted) and create a Virtual Disk Group. In my case I created each one as RAID 0 (with a single drive only) as I just wanted JBOD but there is no such option or default in these Dell Pe........

The dmg format is silly and annoying to work with, why couldn't Apple stick with the .iso standard? Anyway, there's an excellent Linux and Windows based tool to convert it back to a normal .iso Image called dmg2iso
I'll only cover theLinux version although the Windows pre-built binary works the same way.
Download dmg2iso here for free (from the author's website)
It's just silly and doesn't make sense that Ubuntu doe........
