Samba 4.1 Active Directory Domain Controller on FreeBSD 10.1

To simplify home network management, I recently decommissioned my beefy domain controller/file server/Hyper-V host, moving mass file storage to the cloud. I thought I could live without Active Directory, but with 5 PCs and a couple of Windows tablets, I want it back, so my plan is to host a tiny VM instance in hyper-V on 4 of my desktop PCs, creating something like peer-to-peer AD (hopefully with little overhead).

Resources

The following references were incredibly helpful, but neither were perfect for getting up and running quickly, hence this gist.

Installing XenServer 6.2.0 from a USB Stick

Download the XenServer 6.2.0 ISO image
Format a USB stick using FAT32.
Use unetbootin to install the ISO to the USB stick. Use the “DiskImage” option instead of the “Distribution” one, and point it right to the ISO file.
Now we need to fix up some boot stuff (All paths are relative to the root of the USB drive)
