Virtualbox(PUEL) 3.1.6 Host-Only Adaptor connectivity problems

Question

Hi there! I'm a new Arch Linux user and i'm LOVING it ... I've hit one problem I can't seem to get Host-Only Adaptor networking working with VirtualBox (PUEL) with any virtual machines e.g. VM's can't communicate to anything Host machine, router etc, I've set static addresses for all my Vitual machines.
(Host machine)
/etc/conf.d/bridges
# Settings for layer-2 bridges
# For each bridge interface declared in INTERFACES (in rc.conf), declare
# a bridge_${IF} variable that contains the real ethernet interfaces that
# should be bridged togeether.
# Then list the bridge interface name in the BRIDGE_INTERFACES array.
# example:
# in /etc/rc.conf:
# eth0="eth0 up"
# eth1="eth1 up"
# br0="br0 192.168.0.2 netmask 255.255.255.0 up"
# INTERFACES=(lo eth0 eth1 br0)
# in /etc/conf.d/bridges
bridge_br0="eth0 vbox0"
BRIDGE_INTERFACES=(br0)
#bridge_br0="eth0 eth1"
#BRIDGE_INTERFACES=(br0)

I need to use VirtualBox on an almost daily basis for work... I would highly appreciate you help so thanks in advance!

Hi, I'm not sure I fully understand your issue.
Are you telling VirtualBox don't allow you to add a Host-Only Adaptor via main menu File -> Net -> Add button? I once hit this problem and was lost some days because I come from the *buntu-land and all this configuration was nearly automatic there. If this is your problem you should first download and install the rigth AUR package, tha one working for me is virtualbox_bin now at latest version 3.1.8-1, you will need to install also virtualbox-additions. After you installed VirtualBox follow the instructions provided by packagers:
IMPORTANT NOTES:
- Run "vbox_build_module" as root every time your kernel is upgraded, to
  compile the module for the new kernel version.
- Add your user to the vboxusers group:
     gpasswd -a USERNAME vboxusers
- Add "vboxdrv" to the MODULES array in your "/etc/rc.conf"
- Add "vboxnetflt" to MODULES if you want Host Interface networking.
- Add "vboxnetadp" to MODULES if you want Host-Only networking.
- If USB does not work for you out-of-the-box, add the following line
  to "/etc/fstab":
     none /proc/bus/usb usbfs auto,busgid=108,busmode=0775,devgid=108,devmode=0664 0 0
Once you do that you'll be smoooooth 8-D
