Hi,
The above solution didn't work for me, However
I had the same issue on a HP dl360p Gen 8, it turns out the SPP ( Service Pack for Proliant ) doesn't include updates for the BIOS and the ILO 4.
After updating both ( although I'm pretty sure the BIOS is. what fixed it ) vmware loaded and ran OK.
BIOS for DL360p Gen 8. can be found here

ILO-4 firmware can be found here

I upgraded the ILO first then extract the BIOS download files ( I used 7zip for this ) then from the ILO Admin then firmware and select
CPQJ0613.684
After it completed it loaded vmware 8.1 without any issues so far ( about 5 days ) it's running fine.
Hope this helps!
