Is MultiOS supported under FreeBSD, because it’s failing to work in FreeBSD 9, 10 or 11 current, panicing the kernel. This is under Xen 4.5.0 using either xen-qemu-traditional or qemu-xen. Both using secondary passthrough.
This is either with a Quadro 2000 or FX3800, both with appropriate Quadro drivers. The same cards are fine under Linux (debian).
