If you have Veeam, give them a call there techs are top notch!

some things i would check

Did i have specific hardware on other host, like Pass-Thru, hard drive or modem?

Is there enough space to expand about 10% for esxi to startup?

is the RAM allocation changed? did i start with 10 and reduce to 6?

VM hardware version the same or higher then the host requirements?

make sure if you were running ESXi 5.1.1 that i atleast use that version to restore into?

Take a deep breath and think my friend. ill monitor and try to help!

The original had 504MB CPUs 2 and BusLogic Parallel.  So everything is the same other then yes the hardware changed.

It was a Cisco UCS blade and restoring to a Dell PowerEdge Server

well i would also try and boot with VMware player on a laptop, just to test.

try another image if you have one to ensure its not a bad image.

Are you restoring on the fly or disk to disk with proxy?

Are the VMWare hardware versions the same? Is the ESXI version the same? If it was BIOS or EFI boot before, is the boot method still the same?
