HP ML110G6 dual boot: VMware ESXi and Microsoft Hyper-V Server 2008 R2

I have been working with VMware products for many years. Recently, I decided to extend my home lab and bought a HP ML 110 G6 server . These HP servers are a good choice for a home lab, they have the look and feel of the enterprise stuff, are affordable and are pretty able to run VMware ESXi (although the compatibility of the G5 was better…).

VMware ESXi is the future, I found this great blogpost,  Installing VMware ESXi 4.0 on a USB Memory Stick “The Official Way” , plugged a memory stick in the internal USB connector, installed ESXi, created a local VMFS partition and started creating VM’s.

I think one has to be independent and it is always good to know how other vendors (especially in the field of Virtualization are doing). And the best way is to download and install, in my case, first on my list is Microsoft Hyper-V server 2008 R2. And it would be nice to have both on the same hardware, just like in the old days with a dual boot Windows/Linux PC…

So after downloading and burning a DVD, I have followed these steps:

  • Make sure the local VMFS partition is empty. In my case, VM’s  run on shared storage, the local partition was as good as unused.
  • Check the BIOS and make sure that under Advanced -> Harddisk Configuration -> SATA mode selection is on AHCI. Microsoft Hyper-V server 2008 R2 won’t install in “Compatible”mode.
  • Also check the Boot options, in my case:
  • Boot the Windows DVD, follow the instructions. Format the local disk, create a new partition to install Hyper-V (60 GB) and leave the rest available to create a new VMFS partition
  • On first reboot, ESXi started, instead of Hyper-V. Even after several attempts to change the boot order (Removable Devices in first position) gave the same result. After unplugging the memory stick from its internal USB adapter, I had my first chance to see Hyper-V in action.
  • Finally, I have decided to plug the memory stick in one of the external USB adapters, to be able to boot ESXi, and to leave it out to boot Hyper-V.

I guess, this method should work on other hardware. Does anyone know a reliable method to decrease an VMFS partition? Happy reading, I welcome your ideas.
