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!
