OS X Lion, Ubuntu 10.04 Bridged Networking Working Intermittently

I'm running OS X Lion on the New Macbook Air.

I have Parallels v6.0.12094 and I'm running Ubuntu Server 10.04 on it.

I have networking setup a bridged because I need Ubuntu to get its own IP from the router for development purposes.

Sometimes the Ubuntu will get an Internet connection and 192 IP from the router, but more times then not, it will not.

There seems to be no rhyme or reason as to when it works and when it doesn't. I'll reboot Ubuntu 20 times, restart Parallels, reboot my Mac, etc. No one thing seems to fix it, but it will just grab a connection out of thin-air.

Using a Shared connection always allows Ubuntu to connect to the Internet, but this isn't an option for me.

Here is a current screenshot of ifconfig -a

I've spent countless hours trying to solve this problem to no avail.

Things I've tried:
/etc/init.d/networking restart
ifup -a
ifdown -a
Changing the MAC Address of the hardware
Changing bridged connection from Default Adapter to WiFi

If someone can help me out here that would be awesome!

Thank you!

 

Same problem here. The VM doesn't get an IP via DHCP.

I am seeing this as well with 11.04. Interestingly the guest works fine if I configure a network interface statically, it's just DHCP that seems to not be being bridged.
If I use tcpdump on OSX I can see the packets appearing on en0 (wifi), but other machines on my LAN don't see them.
It slightly suggests that OSX is not sending the packets.

 

Hi,

due to nature of the WiFi networking, VM while bridged to WiFi must use host's MAC-address. But some of the WiFi routers doesn't allow DHCP-request that mismatches actual MAC-address.

The reliable way to workaround this is to assign a static IP-address to the guest in VM.

We attempted to provide a solution with "Send Host's MAC-address to DHCP server" option in the network settings, but it works only when wireless adapter is explicitly selected as to be bridged to (it is ignored when Default adapter is selected) and doesn't helps in most of the cases and even sometimes Guest receives Host's IP-address and blocks networking from Mac. Also, in linuxes additional configuration is required. Reffer to http://download.parallels.com/desktop/v5/docs/en/Parallels_Desktop_Users_Guide/28189.htm

So, I recommend to use static IP if you need to bridge to WiFi and SharedNetworking doesn't suite your needs.
