I have a windows Vista machine upon which VirtualBox is running ubuntu.
In ubuntu I am running a webserver at the address http://127.0.0.1:3000/
How do I access this address from my host machine (the windows box)?

You can change your guest networking mode from NAT to Bridged. Just close your Ubuntu guest, go to the Settings page in VirtualBox, select the Network category and change the Attached to listbox from NAT to Bridged Mode.
After following the above steps restart Ubuntu and the allocated IP will show on the welcome screen after load. i.e. In the welcome message it should say something like:
IP address for eth0: 192.168.1.3
Use this address in the browser bar of the host machine followed by the port your using. If its anything other than port 80. i.e. if you set it up to use port 666 then the address would be 192.168.1.3:666
Another way to find the IP is to connect to the HTTP server built into your router and look in LAN settings. Every machine on the network should be listed by host name and IP. On my router most others I've had, you can do this by typing 192.168.1.1 in the address bar. if that fails try same address at port 81. If that fails READ THE MANUAL.
Depends how you setup networking on the Ubuntu guest OS. If you set it up to use NAT and you have a DHCP server running on your network, then just run this:
ifconfig | grep inet
on the Ubuntu box -- you'll see the IP address assigned to the Ubuntu guest.
#ifconfig | grep inet inet addr:10.0.0.2 Bcast:10.255.255.255 Mask:255.255.255.0 inet addr:127.0.0.1 Mask:255.0.0.0
Then just hit up http://10.0.0.2:3000
Your Windows box and the Ubuntu box (whether they are physical or virtual doesn't really matter in this instance) both need to have an IP address on the same subnet so they can talk to one another via TCP/IP. You can assign an additional address to each OS using one of the private IP subnets (see RFC 1918). Once they both have an address on the same subnet, configure the web server to listen on the one you gave Ubuntu, and then use that IP in the browser within Windows to load it up.
The IP you have configured now, 127.0.0.1, is the loopback address for the local network interface. You would never use that address to access something on a different system, only to refer back to the same system you're on. When using a virtual system, treat it just like you would a separate computer from a networking standpoint.
First of all, you need to do what Answer 1 says:
"You can change your guest networking mode from NAT to Bridged. Just close your Ubuntu guest, go to the Settings page in VirtualBox, select the Network category and change the Attached to listbox from NAT to Bridged Mode."
Then, to get your ip address:
On your virtual machine, open a command prompt and do:
ip addr show
You will probably see a line that looks something like this:
inet 192.168.43.96/24 ....
There is also a line before that with
But you don't want that one! You want the 192 address. That's the address of your virtual machine on your local network. It should be accessible by any device hooked up to the same local network.
Now on your host machine, edit the file /etc/hosts (Not ~/etc) The name of the file is hosts (it's not a folder name)
add a line that looks like this:
Now go to your host machine browser and type in myvm.nameofmywebsite.com
Hopefully that will do it!
However, you may have a router that has security features that will get in the way of seeing your local address. What you can try to do is to use your cellphone's hotspot as your network. That works for me. Just remember when you change network on your host machine that you need to restart your virtualbox.
