No network connectivity between host and guests when using bridged adapters

Description
Using this setup:
|
VBox Host | VM1(win2008r2) VM2(win7) VM3(sles11sp2)
|
[virbr0] | [net0] [net0] [eth0]
| | | | |
+----------------+-----------------+------------------'
|
[eth0] |
|
[wlan0] |
|
Problem: No connectivity between any of the VMs or host.
virbr0 is a virtual bridge.
However: strangely enough, dnsmasq (running on the VBox host's virbr0 adapter) is seeing DHCPDISCOVER requests coming in on the bridge interface and sends DHCPOFFERS:
Jan 12 00:20:48 dnsmasq-dhcp[28385]: DHCPDISCOVER(virbr0) 08:00:27:e2:25:11 Jan 12 00:20:48 dnsmasq-dhcp[28385]: DHCPOFFER(virbr0) 192.168.110.136 08:00:27:e2:25:11
Those DHCPOFFERs are not seen by the VMs, since all of them remain unconnected.
I'm currently running VirtualBox 4.2.6 (vanilla download from http://dlc.sun.com.edgesuite.net/virtualbox/4.2.6/VirtualBox-4.2-4.2.6_82870_openSUSE114-1.x86_64.rpm) on openSUSE 12.2. But I had the same issue on 2 earlier versions of VBox and on openSUSE 12.1.

Please reopen if still relevant with a recent VirtualBox release.


I have the same problem. With a Ubuntu 13.04 host (vbox 4.2.12) and a Ubuntu 12.04 guest VM. The VM never receives the DHCPOFFER from the guest dnsmasq. This was workig some time ago... not sure when :-)
