https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D241774 --- Comment #30 from John Hartley <drum@graphica.com.au> --- (In reply to Tommy P from comment #29) Hi Tommy P, my machine is Lenovo X3650 M5 Type 8871 with Intel E5-2697A v4 CPUs. I think this corresponds to "Broadwell Architecture". So it is VT-D HW Virtualisation, with GRUB setup up for PCI Passthrough etc: cat /etc/default/grub # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=3D0 ... GRUB_CMDLINE_LINUX_DEFAULT=3D"quiet splash iommu=3D1 intel_iommu=3Don ipv6.= disable=3D1" GRUB_CMDLINE_LINUX=3D"ipv6.disable=3D1" QEMU / KVM is going fine including PCI pass through (which requires grub GRUB_CMDLINE_LINUX_DEFAULT config above). I have also enabled nested hypervisor support, but have not used it so far. Running combination of: FreeBSD, Ubuntu, Windows and MacOS VMs, without problems (bar this one). Sorry for delayed response I have been working on seeing if I can get backp= ort of your VirtIO fix on 11.3 . Have done all the coding and now testing, unsuccessfully so far :-( . My VirtIO backport included: Merging - virtio.c/.h, balloon & mmio code Adding - endian support code Replacing virtio/pci code with your sub-tree. Not sure why it is not working at this point. Backport of virtio/network code is likely to be harder as this has adopted = CK (concurrency kit) queues and I have not managed to get clean compile. I will post on backport success / failure in our bug thread. Cheers, John Hartley. --=20 You are receiving this mail because: You are the assignee for the bug.=
