Your patch applied cleanly to the working copy of the "bhyve_svm"-project. I was then able to merge with HEAD (using "theirs-full" on one file) and compile the kernel. So, to me it looks OK to commit. Unfortunately, I am still not able to boot CentOS 6.5 using my Phenom 1055T. It produces 200% load on the host CPU, and the emulated machine generates endlessly: ======================================================================================= BUG: soft lockup - CPU#0 stuck for 67s!
