[FIXED]: Solaris 11.1 sru4.6 + VB 4.2.10 = autostart bugs

Postby kburtch » 8. Apr 2013, 23:56

I've been trying to get VirtualBox's autostart service working on Solaris 11.1 without success.
The VM I'm trying to start does run when manually launched, and does have autostart entabled:
Code: Select all   Expand viewCollapse view
vbox@hostname:~$ VBoxManage list -l vms|grep -i auto
Autostart Enabled: on
Autostart Delay: 0


From the log after a reboot:
Code: Select all   Expand viewCollapse view
[ Apr  8 20:59:59 Stopping because service restarting. ]
[ Apr  8 20:59:59 Invalid use of ":kill" as stop method for transient service. ]
[ Apr  8 21:01:58 Executing start method ("/opt/VirtualBox/smf-vboxautostart.sh start"). ]

[ Apr  8 21:01:58 Method "start" exited with status 0. ]


I dug into /opt/VirtualBox/smf-vboxautostart.sh and found a couple things.
First, it loops through all users in the staff group (which I'm not using).
Code: Select all   Expand viewCollapse view
        for VW_USER in `logins -g staff`
(I'm not sure parsing the output of logins without cut or awk is a great idea, since it includes the username, UID, group, GID, and GECOS fields.)

Wouldn't it make a lot more sense to parse the vboxuser group, since that's the group users have to belong to for some of the functionality anyways?
Code: Select all   Expand viewCollapse view
vbox@hostname:~$ diff /opt/VirtualBox/smf-vboxautostart.sh.orig /opt/VirtualBox/smf-vboxautostart.sh
54c54
<         for VW_USER in `logins -g staff`
---
>         for VW_USER in `logins -g vboxuser`


Even with the above modification, autostart fails silently when rebooting the system.
So, digging further into /opt/VirtualBox/smf-vboxautostart.sh, I find the command line being called is:
Code: Select all   Expand viewCollapse view
exec su - "$VW_USER" -c "/opt/VirtualBox/VBoxAutostart --background --start --config \"$VW_CONFIG\" --logrotate \"$VW_ROTATE\" --logsize \"$VW_LOGSIZE\" --loginterval \"$VW_LOGINTERVAL\""


So, since this is being started as the user, I tried running it on the command line with all parameters that would be defined when the script ran:
Code: Select all   Expand viewCollapse view
vbox@hostname:~$ /opt/VirtualBox/VBoxAutostart --background --start --config /etc/vbox/autostart.cfg --logrotate "" --logsize "" --loginterval ""
VBoxAutostart: error: vbox@hostname:~$ echo $?
2


I'm not sure what exit code 2 means, and didn't spot it skimming through the sources (I'm not a C++ coder, so just looked at the VBoxAutostart.cpp/.h, and a couple other headers).
It also doesn't make sense that the method log shows exit 0.

I decided to try it without passing options with null arguments:
Code: Select all   Expand viewCollapse view
vbox@hostname:~$ /opt/VirtualBox/VBoxAutostart --background --start --config /etc/vbox/autostart.cfg

    vbox 10251     1   0 21:52:50 ?           0:00 /opt/VirtualBox/VBoxAutostart --background --start --config /etc/vbox/autostart
So, that worked.

After searching for information on the missing options, I came up completely dry. Here's the code that sets them (also in /opt/VirtualBox/smf-vboxautostart.sh):
Code: Select all   Expand viewCollapse view
# Get svc configuration
VW_CONFIG=`/usr/bin/svcprop -p config/config $SMF_FMRI 2>/dev/null`
 [ $? != 0 ] && VW_CONFIG=
VW_ROTATE=`/usr/bin/svcprop -p config/logrotate $SMF_FMRI 2>/dev/null`
 [ $? != 0 ] && VW_ROTATE=
VW_LOGSIZE=`/usr/bin/svcprop -p config/logsize $SMF_FMRI 2>/dev/null`
 [ $? != 0 ] && VW_LOGSIZE=
VW_LOGINTERVAL=`/usr/bin/svcprop -p config/loginterval $SMF_FMRI 2>/dev/null`
 [ $? != 0 ] && VW_LOGINTERVAL=


Looking at the configurations in the service, I see only config/config exists:
Code: Select all   Expand viewCollapse view
vbox@hostname:~$ svcprop -p config virtualbox/autostart
config/config astring /etc/vbox/autostart.cfg
vbox@hostname:~$


In case someone is curious, here's the content of /etc/vbox/autostart.cfg:
Code: Select all   Expand viewCollapse view
# Default policy is to deny starting a VM, the other option is "allow".
default_policy = deny
#
vbox = {
        allow = true
        startup_delay = 10
}
kburtch = {
        allow = true
        startup_delay = 10
}


Did I miss something in the docs somewhere, or is something missing from the docs (or code)?
Surely /opt/VirtualBox/VBoxAutostart should be able to handle being passed null arguments to options (since the calling script is coded to pass them).

Re: Solaris 11.1 sru4.6 + VB 4.2.10 = possible autostart bug

Postby kburtch » 15. Apr 2013, 20:24

I found/fixed the problem and submitted a ticket:
https://www.virtualbox.org/ticket/11720

To fix, remove "exec" from the loop in smf-vboxautostart.sh and change "staff" to "vboxuser".

It now will start all autostart-enabled VMs for all users in the vboxuser group.
