Issues with bhyve under KVM

Hey all,
I am utterly confused by this one: I am unable to load vmm.ko nested in
KVM. (10.2 on a 2x E5-2620v2 board, linux kernel 4.x for host, kvm/qemu
2.4, proxmox 4.0. Nested bool is set true in module config).
`dmesg` prints a message saying that VT-x is "disabled by BIOS" (I
passed -L and -bios pointed at OVMF just in case it was a strange
SEABIOS compile option) to no change. -cpu is set to host, I have also
tried passing -cpu qemu64,+vmx manually to no change.
(`kldload vmm` does agree - it says features are missing)
Linux appears to have no problems with bringing kvm up nested (I tested
kvm -enable-kvm as well to no complaints). What am I missing?
