Bug Description

Binary package hint: virtualbox-ose

Was using 8.04

Had followed the instructions here to create bridge and vboxN interfaces for host networking

http://www.ubuntugeek.com/how-to-set-up-host-interface-networking-for-virtualbox-on-ubuntu.html

Networking was working in VMs for months without issues.

Upgraded to 9.04 (via 8.10)

vbox0 device not created, appears on virtualbox's host interface list but not on via 'ifconfig vbox0'

no errors on /etc/init.d/virtualbox-ose restart

no errors in 'grep vbox0 /var/log/*'

virtualbox-ose is 2.1.4-dfsg-1ubuntu3
virtualbox-ose-source is 2.1.4-dfsg-1ubuntu3

http://www.virtualbox.org/wiki/Changelog-2.1

under section -

VirtualBox 2.1.0 (released 2008-12-17)

New Host Interface Networking implementations for Windows and Linux hosts with easier setup (replaces TUN/TAP on Linux and manual bridging on Windows)

Selecting pan0 as the host interface appears to work.

See here -

http://www.virtualbox.org/ticket/3518

However

But 'brctl addif pan0 eth0' does not enable VMs to get DHCP addresses or network access.

Selecting br0 (a bridge left over from the 8.10 config) allows one VM to get DHCP and network access.

Not sure why earlier test with br0 allowed only one machine a DHCP address. Have re-tested on fresh boot. Two VMs booted into LTSP after connecting both using host mode with br0 as the interface.

So when upgrading from 8.04 to 9.04 with virtualbox users should.

1. (before upgrading) Make sure that there are no saved states (as it does not resume properly)

2. (after upgrading) Change network adapter from vboxN to br0
