vboxmanage modifyvm "cloud1" --nic2 hostonly --hostonlyadapter1 vboxnet0 not working

Hello Team,

I am facing issues with "vboxmanage modifyvm --nic2 hostonly --hostonlyadapter1 vboxnet0" the error I am getting is due to second interface which is Host-Only and using VBoxManage (CLI).
As soon as I click (Not Select) OK in GUI (Network--> Adapter 2 ----> OK) a quick progress bar comes and vm starts without any issue.
Am I missing something here?

Setup : Clean Setup
OL 7.3 Latest (4.1.12-61.1.28.el7uek.x86_64) + VirtualBox-5.1-5.1.16_113841_el7-1.x86_64 (Latest)

Commands:

Code: Select all

# Create Hostonly Network and DHCPSERVER
VBoxManage hostonlyif create # this will create vboxnet0
VBoxManage hostonlyif ipconfig vboxnet0 --ip 172.30.0.1 --netmask 255.255.255.0 
vboxmanage dhcpserver add --ifname vboxnet0 --ip 172.30.0.10 --netmask 255.255.255.0 --lowerip 172.30.0.11 --upperip 172.30.0.100 --enable
sleep 1

Why are you running the commands in/as root?

This is my home lab, and making a wrapper script for Oracle OpenStack for Oracle Linux demo lab. using "root" will create any issue?

I tried using my personal user but there are other permission issues, which are giving different errors :( , this doesn't seem to be "root" type of issue. As using CLI I can create hostonlyif and everything gets populated in Network Manager. Problem is when I attach the "hostonlyadapter1" it doesn't pickup "vboxnet0" .

From GUI, I can just select the Guest, Click Settings, and Click OK. A quick progress bar appears and VM can not poweron.

Root has a different permission level when creating files and not one that the normal user has access to. You now need to fix the permission issues to be able to get this fixed.

Are you going to enlighten us or are you going to keep the errors for yourself? ;)

The reason that I'm asking is that don't seem to realize that VirtualBox runs under the user-context. Being root not only doesn't give you additional powers, it completely changes the user-context under which the commands are run and which configuration files are modified.

VirtualBox uses the "/home/<user>/.config/VirtualBox" files for its global configuration and the "/home/<user>/VirtualBox VMs/<VM>/<VM>.vbox" for the VM configuration. If you run as "root", then you're modifying something entirely different than what you intended to.

I am sorry, do not intend to keep the permission errors to myself. Since this is my home LAB I am superuser :D
For Example, my VirtualBox config folder is "/root/.config/VirtualBox" and my iso files and "Default Machine Floder" is /home/virtualboxvms

(PS - Unfortunately creating a custom OL7 iso right now, so cannot switch user safely) I will get back on this tomorrow.
