IP Address Using GuestProperty

[shrikane]

I have question related to getting IP address, I referred to this answer already but I was not able to still fix it,
viewtopic.php?f=34&t=65910

Host Machine : Windows 8
Guest : Slitaz 4.0
VirtualBox : 4.3.24
VirtualBox Java API : 4.3
Adapter in VM : Host Only Adapter

I have created a Java program using API and I can basically connect, clone and start a VM in VirtualBox. But what I was not able to do is get the IP address of machine. (Why I need IP is because I want to SSH into that machine, using JSCH java library and execute some processes)

This is what I tried so far,

1. Based on the link, I tried

Code: Select all

machine.getGuestPropertyValue("/VirtualBox/GuestInfo/Net/<nicid>/V4/IP") - returns empty result
machine.getGuestPropertyValue("/VirtualBox/GuestInfo/Net/Count") - returns empty result
machine.getGuestPropertyValue("/VirtualBox/GuestInfo/Net/<nicid>/MAC") - return empty result
machine.getGuestPropertyValue("/VirtualBox/GuestInfo/OS/Release") - this gives me release version of linux - which is ok

2. I tried this one more thing, how many properties are exactly available

Code: Select all

org.virtualbox_4_3.Holder<List<String>> tempList = new Holder<List<String>>();
org.virtualbox_4_3.Holder<List<String>> tempList1 = new Holder<List<String>>();
Holder<List<Long>> tempList2 = new Holder<List<Long>>();
org.virtualbox_4_3.Holder<List<String>> tempList3 = new Holder<List<String>>();
machine.enumerateGuestProperties("",tempList, tempList1,tempList2,tempList3);

Now in templist, I get name of all properties available and in tempList1 it's values.

[/VirtualBox/GuestInfo/OS/Product, /VirtualBox/HostInfo/GUI/LanguageID, /VirtualBox/HostInfo/VBoxVerExt, /VirtualBox/GuestAdd/Vbgl/Video/SavedMode, /VirtualBox/GuestInfo/OS/Version, /VirtualBox/GuestAdd/VersionExt, /VirtualBox/GuestAdd/Revision, /VirtualBox/HostGuest/SysprepExec, /VirtualBox/GuestAdd/Vbgl/Video/0, /VirtualBox/HostGuest/SysprepArgs, /VirtualBox/GuestAdd/Version, /VirtualBox/HostInfo/VBoxRev, /VirtualBox/HostInfo/VBoxVer, /VirtualBox/GuestInfo/OS/Release, /VirtualBox/GuestAdd/HostVerLastChecked]

3. That is the reason, I think this works

Code: Select all

machine.getGuestPropertyValue("/VirtualBox/GuestInfo/OS/Release") - this gives me release version of linux - which is ok

Now in this list, there is no property related to IP address.

Code: Select all

machine.getGuestPropertyValue("/VirtualBox/GuestInfo/Net/<nicid>/V4/IP")

Also I am not sure what exactly here is nicid and how to get this using API, is it mac address of adapter in VM, or something else.

Can somebody please help me out here or guide in appropriate direction.

One more point to mention, GuestAdditions for Slitaz are already installed

[noteirak]

Double check that:
- The guest additions are installed inside the VM
- Are running
- Are the ones that come with your VirtualBox installation and not from your linux distro repositories <-- most common error
- Match the version of VirtualBox you are uing

If all this is the case:
- Attach a ziped log file of a VM session (VBox.log)
- Give the output of the following commands (replace <vmname>) while the VM is running and is supposed to give you the info :

Code: Select all

vboxmanage showvminfo <vmname> --details
vboxmanage guestproperty enumerate <vmname>

[shrikane]

Thank you for the prompt reply, I will check the details and get back to you immediately.

Really appreciate your help.

[shrikane]

So, regarding the guest additions you asked me to check,
1. First I installed them using this link,viewtopic.php?f=7&t=43286
now when I fire command in my guest Slitaz -
lsmod | grep vbox
vboxvideo
drm
vboxsf
vboxguest
(I am not sure if there is some other way to check if vbox guest additions in guest are installed and what version is it?, please let me know)
2. This is the guest addition iso, I downloaded : VBoxGuestAdditions_4.3.24.iso , download link : http://download.virtualbox.org/virtualbox/4.3.24/
I used this one because, Virtual Box I have is of version 4.3.24r98716

Attached the zip containing logs and output of two commands.

[noteirak]

The log files gave the guest additions version, so it is fine. Everything is matching as it should.
what is the output of the following commands in the guest, all as root :

Code: Select all

ifconfig -a
lsmod | grep vbox
VBoxControl -v

[shrikane]

Here is the output of the commands u asked,


sry for image, somehow irrespective for having guest additions copy pasting is not working

Thanks again

[noteirak]

Well, I'm out of ideas - every requirement that I am aware of is fulfilled, your installation doesn't seem damaged, you're doing things right. I will try to ask a dev and post back in a bit (hours or days).

[shrikane]

Thank you, I appreciate that, in the mean time I will try with Ubuntu as Guest, lets see how things goes.
I will keep you posted, tc

[noteirak]

Few more checks for you :
- Is the time in the host and in the guest in sync?
- What is the output of this in the guest

Code: Select all

sudo /etc/init.d/vboxadd-service status
sudo ps aux | grep -i vbox | grep -v grep

[shrikane]

No time is not in sync, guest is one hour behind than host. I will sync it and try again and get back to you.

And here is the output of commands you asked for

[shrikane]

Nope Syncing time doesn't help as well, I am not sure if you wanted me to do that , but neways I still did that just to see if anything happens but nope still no luck.

[noteirak]

Yes I did wanted you to sync
About the previous command, could you run it as root too? I am not sure you're getting all the processes, even those running as root

[shrikane]

I did run them as root now, but at least I see no difference,

[noteirak]

The process responsible for setting the guest properties about NIC is called VBoxService, which you don't seem to have running. What is the output of this :

Code: Select all

which VBoxService
