Hyper-V An error occurred while attempting to start the selected virtual machine(s)

The physical machine is a HP ProLiant ML 350 G6 running Windows Server Core 2012.  Before this machine was shipped off to production use in another country I set it up and advance with two virtual machines.  Both of them were running fine when it left my office.

When it arrived in the host country and was powered up I could not start the virtual machines giving me the error message Hyper-V An error occurred while attempting to start the selected virtual machine(s).  I have since completely deleted the VM's removed the hyper-v feature, restarted it, re-installed the feature and re-set up the machine from scratch.  I still can not start the VM getting the same error message.

I have verified that both visualization options are enabled in BIOS. (HP BIOS D22)
Intel(R) Virtualization Technology is Enabled
Intel(R) VT-d is enabled

When the machine boots and it shows processor information it states that Hyper threading is enabled.

If I can't get the VM to start today our next option is to re-install the operating system and to try again.  I don't know what else to do at this point.

Computer has decreased RAM during transport? (one module not completely inserted and disconnected by some hit or whatever). Can you "see" virtual machine disks files?

I can see the the disk files fine by browsing through the file structure.  I can also pick the virtual hard drive through hyper v manager.

I can 8 gigs of RAM available (it's what it shipped with... each VM was designated 2 gigs of ram and that is sufficient for what they are doing) so I should have 2 GIGS free.

Apologies, I thought this was updated and closed.

I re-installed the server operating system, re-installed hyper v and re-setup the VM's and it worked fine.  I was surprised a re-install worked but it did.

Re-installing the OS solved the issue.
