...the Intel Core Duo E6600, this CPU was released in 2006... As such, this CPU doesn't have SLAT capabilities and won't support Hyper-V.
When you run Coreinfo, it is easy to misinterpret the output.
If your CPU does support SLAT you will see an asterisk * next to EPT field:
EPT * Supports Intel extended page tables (SLAT)
If your CPU doesn't support SLAT you will see an minus sign - next to EPT field:
EPT - Supports Intel extended page tables (SLAT)
If you don't pay attention to the presence of the asterisk or minus sign, and just focus in on the wording "Supports Intel extended page tables (SLAT" you would misinterpret the reading.
Please run Coreinfo again and I'll bet that you see a minus sign next to EPT field.
