Dears.

I have updated my FreeBSD 11 guest on Virtualbox to rev 298522

FreeBSD nostromo 11.0-CURRENT FreeBSD 11.0-CURRENT #0 r298522: Sun Apr 
24 07:25:34 BRT 2016 ota at nostromo:/usr/obj/usr/src/sys/NOSTROMO  amd64

The virtualbox is 5.0.18 r10667 running on Windows 10. The FreeBSD guest 
is running  virtualbox additions

virtualbox-ose-additions-4.3.38 VirtualBox additions for FreeBSD guests

I'm using this machine to build FreeBSD images to Beaglebone Black using 
crouchet and cross compile packages using poudriere. I have finished a 
full build of FreeBSD 11 r298522 to Beaglebone and actually I'm 
upgrading my poudriere jail to 298522. Until now all runs fine. This is 
my conf of kernels:

Until now both machines are running without problems and with full 
stress. The Beaglebone is compiling kernel and the amd64 have compiled 
freebsd to beaglebone. If exists some tests that I can made to help 
please let me know.
