https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D236922 --- Comment #4 from Tommy P <tommyhp2@gmail.com> --- (In reply to Kubilay Kocak from comment #2) 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): https://packages.ubuntu.com/search?keywords=3Dqemu Aside from that, it still doesn't explain why the original kernel (r341666) from the install ISO did not detect the VirtIO PCI controllers while the cu= stom built updated from src (r345757) did detect the VirtIO PCI controllers when= the diff comparison of src/sys/dev/virtio doesn't show any changes. If anythin= g, I'd expect the custom built kernel not to detect any VirtIO PCI controllers like the original kernel of the install. Since the custom kernel did in fa= ct the detect the VirtIO PCI controllers, it lead me to believe that the drive= rs are not working correctly. To confirm that the virtio drivers are loaded, I got this: root@fbsd12:~ # kldload virtio kldload: can't load virtio: module already loaded or in kernel yet: root@fbsd12:~ # kldstat Id Refs Address Size Name 1 10 0xffffffff80200000 1099a70 kernel 2 1 0xffffffff8129b000 372508 zfs.ko 3 2 0xffffffff8160e000 a2e8 opensolaris.ko when 'pciconf -lvce' shows the VirtIO PCI controllers. I've attached the /var/log/messages file with verbose logging on boot as requested. As side note, I was able to install just about every guest OS (Fedora, Ubuntu, and Windows 2008 R2 to Windows 2016) successfully utilizing the Q35 chipset and VirtIO HDD+NIC --=20 You are receiving this mail because: You are the assignee for the bug.=
