Thank you. Changing file permissions reduced the time to load the virtual box module by about 10 seconds.

@Anselmo,

I have Virtual Box configured on several servers, and do not recall having problems loading the “vboxdrv” during boot.

But here are things you can try.

Try to re-setup the module:

sudo /etc/init.d/vboxdrv setup

Also double check that the module have the right permissions, if not:

chmod 660 /dev/vboxdrv
chgrp vboxusers /dev/vboxdrv

I found out what is delaying my boot. It is the loading of the Virtual Box kernel module. However, I don’t know how to disable it. I have already included it in the file /etc/modprobe.d/blacklist, but it is still loading at the boot. How should I do to make it not load? The kernel module name is vboxdrv. TNX in advance.

@Anselmo,

If that is your configuration, network is not your problem during the startup.

So we can look deeper. While the system is booting up (splash screen), can you press “Ctrl + F1″, and then either “Ctrl + F8″ or “Ctrl + F7″, so you can see the actual boot process.

Pay attention to what takes the most amount of time, and post back with comments.

I configure my connections through the gnome network manager (nm). It seems that nm does ist own configuration, but I’m not certain.

My /etc/network/interfaces:

auto lo
iface lo inet loopback
#iface eth0 inet static
#address 192.168.0.20
#netmask 255.255.255.0
#gateway 192.168.0.1

Can you post your “/etc/network/interfaces”?

The thing to also check is while booting up, click “Ctrl+Alt+F8″ (can be “Ctrl+Alt+F7″ depending on the configuration), and see what “stage” is actually taking so long to boot. The thing is it may not just been the “networking startup” time.

Let me know,

It asks a DHCP server for one, and I have two interfaces: lan and wlan.

@Anselmo,

How do you have your network configured? Is it getting a static IP, or asks DHCP server for one? How many cards do you have (lan + wifi)?

The above method of “paralleling” processes works on several boxes for me.
