There's a bug here. That should be return (error). That's been breaking

3 months?
Fixed in commit b13335331092, thanks.
If I'm reading the bhyve code correctly, this is "cosmetic": the
libvmmapi wrapper for this operation is vm_unmap_pptdev_mmio(), called
in bhyve's passthru_mmio_map(). When the ioctl fails,
passthru_mmio_map() prints that warning and returns an error to the
caller... and all callers ignore it. I think that was true even before
my refactoring in commit 86150ed98b790.
How exactly is passthru broken for you?
Was goingt o say see virtualization@ but maybe it's not broken as such as I am
fighting the next issue.
After fixing the ENOENT locally and the errors (or warnings as you say) being
gone,
which I thought may be the cause preventing the next bit, I am still not
getting a
virtio-net device to netboot the guest. The tap interface is there and also
gets
connected but EFI says there is no device to boot from. I am still trying to
debug
that. Help will be appreciated :)
