Hi all, I'm having another issue with my new desktop machine, this time with Virtualbox. I originally sent this to freebsd-emulation a few days ago, but I haven't had any response. I'm hoping someone here can help me. My machine is running FreeBSD 10.2-PRERELEASE #2 r284595 with a GENERIC kernel. I built & installed virtualbox-ose-4.3.28 (and kmod, of course) from ports. /etc/make.conf contains 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 At boot, I now see the following: vboxdrv: fAsync=1 offMin=0x3ae80 offMax=0x3ae80 supdrvGipCreate: omni timer not supported, falling back to synchronous mode I've never seen the supdrvGipCreate message before. I first moved a 32 bit Windows 7 VM from my old desktop which was running a FreeBSD-stable a week or 2 old (literally; I took the drive out of the old machine). The first time I tried to boot the VM it took about 7 minutes. The CPU I allocated to the VM stayed at 100%. After some googling, I turned off hyperthreading in the 7810's BIOS. The VM now boots in a reasonable time and is almost usable. 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. When it 'freezes up' its CPU is at 100%. As a test I started installing a 64 bit Windows 8.1 VM. It behaves exactly the same way. Does anyone have any ideas or suggestions? I'm hoping there's a BIOS setting I can tweak to make this work.
