https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=236922 --- 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=qemu 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 custom 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 anything, 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 fact the detect the VirtIO PCI controllers, it lead me to believe that the drivers 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 -- You are receiving this mail because: You are the assignee for the bug.help
