VirtualBox 5.2.4 & native CD access on FreeBSD 11.1

[Thomas David Rivers]

Having some problems with VirtualBox on FreeBSD 11.1.

I've entered these as tickets on virtualbox.org:

https://www.virtualbox.org/ticket/17424
https://www.virtualbox.org/ticket/17434

But - I can't seem to access the CD-rom natively... VBoxSVC
appears to die.  Just wondering if I might have something
not set-up correctly on FreeBSD 11.1.

I was following the notes from the HandBook (https://www.freebsd.org/doc/handbook/virtualization-host-virtualbox.html) Chapter 21.6.

Note that 'hald' isn't installed by default in FreeBSD 11.1;
I grabbed it from the 11.1 packages.

So - I have 'hald_enable="YES" in /etc/rc.conf, and hald is running:

root at fs1:~ # ps -gax | grep hald
796  -  Ss    0:00.41 /usr/local/sbin/hald
801  -  I     0:00.06 hald-runner
816  -  S     0:00.34 hald-addon-storage: /dev/cd0 (hald-addon-storage)
988  4  S+    0:00.00 grep hald


and I've changed /etc/devfs.conf to provide the proper permissions:

#
# For VirtualBox HAL access to devices
#
perm cd* 0660
perm xpt0 0660
perm pass* 0660


and - the permissions on /dev/cd*, /dev/xpt0 and /dev/pass* are:

root at fs1:/dev #	ls -l cd* xpt* pass*
crw-rw----  1 root  operator  0x54 Jan  8 19:42 cd0
crw-rw----  1 root  operator  0x50 Jan  8 19:42 pass0
crw-rw----  1 root  operator  0x51 Jan  8 19:42 pass1
crw-rw----  1 root  operator  0x52 Jan  8 19:42 pass2
crw-rw----  1 root  operator  0x53 Jan  8 19:42 pass3
crw-rw----  1 root  operator  0x47 Jan  8 19:42 xpt0


Also - the virtualbox user (boxes) is in the group "operator".

When I try to create a new machine in VirtualBox (the latest
5.2.4 package), I then need to read the CD to install the OS.
When I click on the native device (a MITSUMI drive, properly
reported); the virtual machine just goes to "Aborted" state.

Looking in the logs, particularly the VBoxSVC log, I see:

Log created: 2018-01-09T00:38:59.353089000Z
Executable: /usr/local/lib/virtualbox/VBoxSVC
Arg[0]: /usr/local/lib/virtualbox/VBoxSVC
Arg[1]: --auto-shutdown
AddRef: illegal refcnt=3221225469 state=2

and also the VBox.log file reports:


00:00:03.403010 PIT: mode=2 count=0x10000 (65536) - 18.20 Hz (ch=0)
00:00:03.403464 VMMDev: Guest Log: BIOS: Boot : bseqnr=1, bootseq=0321

00:00:03.406181 VMMDev: Guest Log: Could not read from the boot medium! System halted.

(unfortunately, it doesn't bother to report why it couldn't
read from the CD-ROM.)


There is a VBoxSVC.core file created, and gdb of that doesn't
reveal too much beyond an un-caught SIGTRAP:

So - does someone have good luck accessing the host CD drive
in VirtualBox under FreeBSD 11.1?  I'm guessing it has to be
some config problem somewhere, so if someone has some pointers
of where to look; it would be appreciated!
