http://ubuntuforums.org – Hi there. I have a strange problem here. I've set up ubuntu server 10.04 x64 with kvm and bridged networking and installed win server 2008 as a guest os. The guest os has full access to the network including lan/wan but the host os can only reach my lan and not the wan. This is true even when the guest machine is powered off? I have to admit that my knowledge of networking, particularly with respect to linux is very flakey but surely if the guest has internet access this should also apply to the host? My only suggestion is an issue with mac addresses but i don't know where to start. Has anybo (HowTos)

I have virtualbox 4.1 on a ubuntu 12.04 host. On my host I have a virtual interface eth0:1 configurend as 10.0.1.1. I have a few virtual machines using bridged adapters, configured in the 10.0.1.0 net which I can reach (ping, ssh, ...) from my host via the virtual interface.

Now I installed an ubuntu server 12.04 in a virtual box, again using bridged adapter, but I can not reach that host.

Hi there,Have setup a CentOS 6.3 KVM server (host) but my guest (same distro) can't access the internet.The host can ping the guest, other servers on the LAN and 8.8.8.... [by JackStone]

Heya All,

I am running VirtualBox 3.2.8_OSE r64453 on Lubuntu 10.10, running an Ubuntu Server 12.04 install, and wish to allow communication from host to guest, as well as guest to network. However, while the guest can communicate with the host, that is as far as communications go. I have the guest set up with two adapters; one NAT, and one Bridged (tried Host-Only as well), but to no avail.

I have several virtualbox applicances (windows, linux) each of them configured with two network adapters:

NAT for acessing the internet host-only for hosts <> hosts and hosts <> guest communication

Problem is, I can conly communicate by ip address. I want to communicate by hostname, ie, I want to be able to reach any host from any other host (or guest) by using the hostname.

I have virtualbox running on a Windows 2008 server, with a guest running ubuntu 10.04. The ubuntu guest is given a static IP of 192.168.1.4, which also has openssh installed. The guest has bridged network setup, I can ping 192.168.1.4 from any machine in the LAN, the ubuntu guest can also access the LAN. However, when I try to PuTTY into the ubuntu machine, I always get "connection refused".

I have installed and setup a guest Mageia 2 on VirtualBox which I plan to use as a development web server. My host is Windows 7 (64-bit) and I want to access the web sites from this host web browser.

I have set VirtualBox Network setting of Mageia guest OS to "Bridged Adapter" and I took the IP address of eth0 and entered that on my host web browser.

I have an Ubuntu Server machine which is acting as a VM host for KVM guests made with vmbuilder. I want to expose the VM's to the network. Currently, the VM guest can get out to the network, and I can get in to the VM from the host, but I can not access the VM from the outside.

On the host, I have set up a bridge br0 which includes the physical interface.

Background I have a lab setup in which the guest OS uses postfix as an MTA. Now my host is connected to a Terminal server which for now is on LAN (A lab). Guest has different servers which are needed for authentication, authorization, communication, scheduling...The only thing can't work is MTA because guest is bridged to LAN card.

Hi there, I have a problem with guess host use Bridged Network on VMWare. I install the guest OS CentOS (192.168.1.37 )on host Windows XP SP2 (192.168.1.33), I try to use bridged-connection so the guess can appears as an additional server on the same physical Ethernet network as my host. My problem is:
