            Bug ID: 224003
           Summary: xen kernel panics
           Product: Base System
           Version: 11.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: rnestor@tx.rr.com

Picked up an Antsle device/system designed to host VMs.  It comes with Gent=
oo
Linux and runs KVM and Linux LXC images and can run FreeBSD in a KVM VM.

Paved over Gentoo with LinuxMint 18.3 and installed Xen.  All runs OK, but
wanted to try the same with FreeBSD as the Dom0.

Downloaded and installed the 11.1 Release then followed the instructions for
loading and running Xen as a Dom0.  When booting up the Xen Hypervisor it
panics claiming the IOMMU isn't present or enabled.  There's no option in t=
he
BIOS it enable this, but clearly it's present and enabled since Xen under
LinuxMint ran.
