Ubuntu 14.04 installation on Dell Vostro 1000 (Broadcom BCM4311)

Enable ethernet networking (20th of April, 2014)

Problem: after the installation the ethernet network doesn’t work anymore

Open a terminal and enter the following commands:

  1. echo “blacklist wl” | sudo tee -a /etc/modprobe.d/blacklist.conf
  2. sudo mv /etc/modprobe.d/blacklist-bcm43.conf /home/$USER
  3. Switch of the notebook and restart.

The network is restored.

Wireless Install
sudo apt-get install firmware-b43-installer

How to convert a VMware image to VirtualBox

It is very easy to convert a VMware image to VirtualBox. Just use VBoxManage which is incuded in Virtualbox.

VBoxManage clonehd –format vdi old_vmware_image.vmdk new_virtualbox_image.vdi

Adding the converted image to VirtualBox:

  1. Add a new project in VirtualBox.
  2. Move the converted image new_virtualbox_image.vdi into the new directory /home/$USER/VirtualBox VMs/NameOfYourNewVirtualbox created by VirtualBox.
  3. Select this image with the file selector.

In my case it was important to leave the MAC address predefined as suggested by VirtualBox.

Virtualbox sharing folders (with NFS), Ubuntu 13.10

After quite some hassles trying to activate the regular Virtualbox folder sharing (between host and guest operating system) I decided to try NFS. Actually it worked pretty well. You can use all the benefits of NFS. I set the guest operating system to the “Bridged networking” to access my guest box via an internal ip. The following information works for a Linux host and guest.

Guest OS:
sudo apt-get install nfs-kernel-server

add this line to /etc/exports (e.g. IP 192.168.0.20 of host OS)
/home/username/sharedfolder 192.168.0.20(rw,async)

Host OS:
sudo apt-get install nfs-common

mount the NFS drive (e.g. IP 192.168.0.21 of guest OS)
mkdir /home/username_host_os/sharedfolder
sudo mount 192.168.0.21:/home/username_guest_os/sharedfolder /home/username_host_os/sharedfolder

unmount the drive when you don’t need it anymore
sudo umount /home/username_host_os/sharedfolder

Remark: The IPs can be easily looked up via the network manager applet.

Virtualbox Installation, Ubuntu 13.10

As VMware sometimes has problems supporting the newest Linux kernel (in my experience), I moved to Virtualbox which seems better suited for the cutting edge Ubuntu version.

First of all I would recommend installing the newest software package from the Virtualbox website: https://www.virtualbox.org/wiki/Linux_Downloads

When adding a repository you can use the raring repository for Ubuntu 13.10:

deb http://download.virtualbox.org/virtualbox/debian raring contrib

Virtualbox has quite a good manual online for installation issues: https://www.virtualbox.org/manual/

For stuff like USB 2.0 support it is necessary to install the VirtualBox Oracle VM VirtualBox Extension Pack (Note the correct link “All supported platforms”!).

To let the guest vm use the USB devices of the host system you will have to add your host user to the vboxusers group:

sudo usermod -G vboxusers -a $USER

Afterwards it is might necessary to log out and start your windows session again.

Add your USB device that you want to use in Virtualbox and start your vm guest system.
