It's not supported. See https://wiki.freebsd.org/Xen

Known Limitations​

  • Suspend and Resume may not work
  • The console mouse may not work on the host
  • The FreeBSD kernel debugger may not work
  • MSI-X PV interrupts are not supported (FreeBSD)
  • PCI devices with virtual functions work inconsistently (FreeBSD)
  • PCI Passthrough is not supported (Xen/FreeBSD)
  • ARM64 is not supported
  • Loading vmm.ko will panic the Dom0, as may VirtualBox
 
There is barely any interest in Xen Dom0 since FreeBSD got bhyve. Afaik, royger@ is the only person working on it, so you can email your questions directly to him. That said, pci passthrough definitely won't work, I'll be amazed if Xen Dom0 runs at all.
