Hello, My system is an amd64 box running FreeBSD 9.0-RELEASE on top of ZFS. I try to setup a VirtualBox VM from an Ubuntu 12.04 Server installation CD in a headless mode using VNC. Top shows that VBoxHeadless process consumes 100% CPU almost all the time and it takes forever to boot from the CD image: PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 1652 vbox 19 22 0 358M 170M IPRT S 3 7:18 100.00% VBoxHeadless I get lots of repeating "ioctl(7,0x200056c1 { IO 0x56('V'), 193, 0 },0x0) = 0 (0x0)" lines every time I try to run truss on the running VBoxHeadless process, like this: ioctl(7,0x200056c1 { IO 0x56('V'), 193, 0 },0x0) = 0 (0x0) ioctl(7,0x200056c1 { IO 0x56('V'), 193, 0 },0x0) = 0 (0x0) ioctl(7,0x200056c1 { IO 0x56('V'), 193, 0 },0x0) = 0 (0x0) ioctl(7,0x200056c1 { IO 0x56('V'), 193, 0 },0x0) = 0 (0x0) ioctl(7,0x200056c1 { IO 0x56('V'), 193, 0 },0x0) = 0 (0x0) ioctl(7,0x200056c1 { IO 0x56('V'), 193, 0 },0x0) = 0 (0x0) ioctl(7,0x200056c1 { IO 0x56('V'), 193, 0 },0x0) = 0 (0x0) ioctl(7,0x200056c1 { IO 0x56('V'), 193, 0 },0x0) = 0 (0x0) ioctl(7,0x200056c1 { IO 0x56('V'), 193, 0 },0x0) = 0 (0x0) ioctl(7,0x200056c1 { IO 0x56('V'), 193, 0 },0x0) = 0 (0x0) ioctl(7,0x200056c1 { IO 0x56('V'), 193, 0 },0x0) = 0 (0x0) and it looks like this system call prevails in truss stats: [root@ci ~]# wc -l truss.vbox.log 1174962 truss.vbox.log [root@ci ~]# cat truss.vbox.log | grep 'ioctl(7,0x200056c1' | wc -l 1013997 [root@ci ~]# FD 7 is /dev/vboxdrv0, does this indicate a problem in communicating with a kernel VirtualBox driver? What should I do to resolve this situation? Thank you! -- SY, Alex
