Fix for vCPU on AMD using bhyve

[Mikkel]

How do I go about adding this fix https://reviews.freebsd.org/D13780 to FreeNAS? Never tried patch management in FreeNAS.

Right now bhyve does not work with more than 1 vCPU if the CPU is AMD. That patch should fix it but I would rather not wait until it trickles down to FreeNAS.

You will have to recompile bhyve with the revised code, and then replace the bhyve binary files in FreeNAS.

So a standard recompile in FreeBSD 11.1 and just replace the binaries on the FreeNAS USBs? That was easy :)

It might be slightly more complicated than that, I'm not sure what funky things the FreeNAS team may have done to bhyve. One of the dev team might chime in here to give you more details. However, I'm going to go with recompile and drop in :)

Just saw this now - https://redmine.ixsystems.com/issues/25131

Unfortunately they also thought it was a Windows OS thing when in reality it was an AMD CPU thing, any guest OS was affected. Once I corrected that on the FreeBSD bugzilla the ball got rolling https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=215972

I would love for FreeNAS to push an update out as soon as possible, so we AMD CPU guys can use bhyve properly :D

Well you can install on 1vCPU and then run on as many as you want/need.
