Cannot install Ubuntu VM on Xeon 5355 running freenas 11.3U3.2

[keithg]

Running FreeNAS-11.3-U3.2 on a Dell 490 with 32Gb of ECC ram. No problems, but want to install a Pi-hole on it and need to create it in a VM. I have never tried this before, but thought that my Intel Xeon 5333 could support virtualization. I went thru the bios settings and it appears that virtualization is enabled. The CPU is
reported as :"Intel(R) Xeon(R) CPU X5355 @ 2.66GHz "

When I try to install a ubuntu Server VM, I get this error: "[EINVAL] vm_create: This system does not support virtualization."

Why does this not work?

Usually, this is because the CPU doesn't support extended page tables (EPT) for 2nd-level address translation (SLAT). In the bootup dmesg output, the CPU will need to report virtualization capabilities like so:

Code:

  VT-x: ...,EPT,...

The Intel ARK datasheet for the X5355 CPU shows it doesn't have EPT support:

• Intel® VT-x with Extended Page Tables (EPT) ‡No

@Samuel Tai Thanks for the help! Bummer that this processor does not support it.
