The kernel sources in that repo are rather old so perhaps your SATA issues is
related to that.
If you tried the modules built from that repo but with newer FreeBSD then
that's probably not going

Hi Brian,
I've just built the kernel using the entire src tree from Git. The buildkernel
was successful. Upon reboot, I think the Virtio PCI are detected

virtio_pci_if.h is supposed to be generated as a part of the kernel build

Hi Bryan,
Thank you for the feedback. I've been digging further to learn more about the
FreeBSD's internal while improving my C/C++ skills. I've found that

The device IDs you are seeing are for the VirtIO V1 spec. FreeBSD only supports
the pre-V1 (aka legacy) VirtIO spec. I suppose there was a QEMU change to use
V1 with Q35 chipset.
I have some rather

Upon further investigation, I did a quick and dirty hack of the source code:
pci/virtio_pci.c:247:/* if (pci_get_revid(dev) != VIRTIO_PCI_ABI_VERSION) */

After reviewing the Linux code for the virtio, I'm more confident that my hunch
is correct regarding the FreeBSD virtio driver.

I think I may found the bug... Please correct me if I'm wrong since it's been
a very long time since I've dealt with C/C++ :(
File src/sys/dev/virtio/pci/virtio_pci.h has this:

Thank you for the feedback. I'm hesitant to try QEMU 4.0 since it's not
officially supported on Ubuntu (even the current 18.10):

PS: I forgot to mention that I did a diff of src/sys/dev/virtio of the original
src during install (presumably r341666) against the updated src (r345757) via
svnlite checkout of 12.0. diff reported no
