#11385 closed defect (obsolete)

No network connectivity between host and guests when using bridged adapters

Reported by: gnyers Owned by:
Component: network Version: VirtualBox 4.2.6

Guest type: all Host type: Linux

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.

I have the same problem. With a Ubuntu 13.04 host (vbox 4.2.18) 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 :-)
