Unknown error creating VM (VERR_HOSTIF_INIT_FAILED)
November 25th, 2007
If you are getting this error:
Unknown error creating VM (VERR_HOSTIF_INIT_FAILED).
VBox status code: -3100 (VERR_HOSTIF_INIT_FAILED).
while trying to start your VirtualBox on Ubuntu, then it's probably because the user by which VirtualBox is running does not have read/write permissions on /dev/net/tun. To solve the problem run this commands:
then add the user that is going to use VirtualBox to the vboxusers group. Run the following command:
Find the vboxusers group:
And add all the users that will use VirtualBox into it:
Save the file and exit gedit. You should not get this error any more.

January 18th, 2008 at 10:27 pm Still getting it on my ubuntu 7.10 install too... followed the directions posted here:

July 5th, 2008 at 1:56 am In my case, my "setup application" for TAP interface caused this error. Probably because I already had the tap1/br0 interface up *before* trying to start the VM.
August 18th, 2008 at 5:41 am Adding a user to a group by editing the /etc/group file is the wrong way to go about things. It's much better to use the command designed for that:
sudo usermod -a -G vboxusers some_username

Even after updating the above changes Vbox does not run. Create a new configuration with "IO-APIC disabled"
It worked for me.
