(In reply to Tsaukpaetra from comment #1)
I have WIP to fix that very issue, but first I had to fix several issues th=
at
do not even allow us to go above 21 or 24 CPU's, corrections for that which
allow
us to go up to 254 vCPU are now in review:
https://reviews.freebsd.org/D18815
https://reviews.freebsd.org/D18816
https://reviews.freebsd.org/D18998

and first steps in removing VM_MAXCPU are also in review:
https://reviews.freebsd.org/D18846
https://reviews.freebsd.org/D18755

Also you do not need to rebuild the kernel, there is a shorter list of
what needs to be rebuilt.  The most overlooked one is to run (cd /usr/src; =
make
includes) so that the change of vmm.h gets installed into /usr/include, aft=
er
that you just need to rebuild vmm.ko, libvmmapi, and bhyve/bhyveload.

This work is still not merged to stable/11, iirc I ran into other interveni=
ng
commits that have blocked that merge.
