I built & installed virtualbox from ports. I'm also running a GENERIC kernal. The only build-related options I have in /etc/make.conf are: NO_LPR=yes NO_PROFILE= true CUPS_OVERWRITE_BASE=yes OPTIONS_SET= OPTIMIZED_CFLAGS OPTIONS_UNSET= NLS ############ DEFAULT_VERSIONS=python=2.7 python2=2.7 gcc=4.9 bdb=5 perl=5.22 Virtualbox builds and install without complaint. However, my 32-bit 1-CPU Windows 7 VM that I moved from my previous workstation is acting strangely. It boots & runs, but performance is terrible. It'll be ok for 2 or 3 seconds, then almost freeze up for a little while (so far always less than a minute), and then be ok again for a few seconds. 'Almost freeze up' means Windows stops responding to the mouse, or the busy indicator spins a quarter of a revolution, then stops, then moves a little more... When I first tried running it, I had left hyperthreading turned on in the 7810's BIOS. The VM took over 5 minutes to boot, and was unusable. It would eventually respond to a mouse event, though, so it wasn't completely hung. Disabling hyperthreading made the VM usable, but just barely. The only other difference I've seen with my previous desktop machine is at boot time. I'm now getting the message when vboxdrv loads: vboxdrv: fAsync=1 offMin=0x3ae80 offMax=0x3ae80 supdrvGipCreate: omni timer not supported, falling back to synchronous mode I've not seen the 'supdrvGipCreate' message before.
