PEBKAC: Virtualization disabled on Pentium Gold G5420? (MicroServer Gen10 Plus)
EDIT: PEBKAC - it was user error! Since i can't just delete this post myself, i might as well share my embarrasment with you. I chose the wrong settings for my VM - OPNsense/FreeBSD really needs its good old i44oFX chipset and legacy BIOS mode (doesn't find its PCI devices with Q35+UEFI.) Just ignore the following.
I'm having problems with passing-through a PCIe device to a virtual machine VM.
I did enable intel_iommu=on (Linux kernel boot parameter), and the IOMMU groups check out as well.
Now i've read this forum article What’s new with the small but mighty HPE ProLiant MicroServer Gen10 Plus? - in the Compute paragraph, it states that "[..]virtualisation software support now includes VMware ESXi with the Xeon processor[..]".
I know that the G5420 should technically be able - it has the VT-d (directed I/O), and VT-x feature set.
Does that mean that virtualization support is artificially disabled on the Pentium Gold G5420 model?
Any other ideas, why the guest OS (VM) wouldn't "see" those two Intel i350 NIC ports?
