Problem with virtualbox on FreeBSD 10-BETA1

[Гуляев Гоша]

   Good day!

   I have a troubles with VirtualBox on my PC:
   Hardware: 8Gb RAM , Intel Core Quad 6300
   OS: FreeBSD 10-Beta1 AMD64 (today's svnup'ed and rebuilded world and
   kernel)
   uname -a: FreeBSD BSD-VBOX 10.0-BETA1 FreeBSD 10.0-BETA1 #0: Thu Oct 17
   22:04:29 MSK 2013 mike at BSD-VBOX:/usr/obj/usr/src/sys/BSDSERV amd64
   I do:
   1. svnup system sources
   2. steps to buildworld and install it
   3. Install VirtualBox 4.2.18
   options for install: DBUS, UDPTUNNEL, VNC
   4. add to /boot/loader.conf
   vboxdrv_load="YES"
   5. add to /etc/rc.conf
   vboxnet_enable="YES"
   dbus_enable="YES"
   6. add my user to vboxusers
   7. after reboot:
   kldstat | grep -i vbox
   3 3 0xffffffff80aa3000 51400 vboxdrv.ko
   4 2 0xffffffff80c12000 29c0 vboxnetflt.ko
   7 1 0xffffffff80c20000 3f30 vboxnetadp.ko
   8. When I try to do something with VboxManage, I get that error:
   VboxManage list ostypes
   VBoxManage: error: Failed to create the VirtualBox object!
   VBoxManage: error: Code NS_ERROR_ABORT (0x80004004) - Operation aborted
   (extended info not available)
   VBoxManage: error: Most likely, the VirtualBox COM server is not
   running or failed to start.

   Also I'm try various recommendations (rm -rf /tmp/.vbox* ; rm -rf
   ~/.VirtualBox )

   In the freebsd-emulator@ someone else confirm that he has similar issue
   with VirtualBox on 10-BETA1
