Fedora network problem in SUN VirtualBox


Hello
I need your help. My machine has a MSN SLI motherboard with a AMD 64Bit Dual Core Processor, four 1.5TB drives, 8G memory and a build-in NVIDIA network controller. The host OS is windows VISTA Ultimate and is working great. I have install Fedora 8 and Fedora 10 guess VMs . My problem is, I can not get the network working on either guess VMs in VirtualBox 2.1.0. I tested Fedora 8 on a Dell laptop and everything including the network works without any problems so I believe there is something in VirtualBox I need to still do. I have tried configuring all four versions of the virtual network adapter hardware in VirtualBox with out any success. If anyone is running or successfully configure a network with this type of system can you please post the steps you used to get your VM network working. BTW I am posting this on both LinuxQuestions.org and forums.virtualbox.org. Thanks for any help…

What sort of network adapter settings are using?
Have you tried using NAT? Are you selecting the proper interface?
A few questions that you might need to answer for me to understand

I can ping the host from the VM

1. Windows device manager it says NVIDIA nForce Networking controller
2. I have tried NAT, Host Interface Networking and also Internal Networking. In the VM when I ifconfig I get the following information:
inet addr: 10.0.2.15 Bcase 10.0.2.255 Mask: 255.255.255.0
I also can ping the host (VISTA) IP address from within the VM but can not ping or connect to the web.

Well, if you are able to ping the host, I presume it is not a problem with VirtualBox.
hmm...
Do you have any sort of AV/Firewall blocking this on Vista?

Question Can ping other machines on my LAN

I also was able to ping other hardware machines (by IP address only) on my LAN from the VM. I just can not ping or access the internet.

If I understand this correct you are able to ping LAN machines, like 192.168.*.*
This makes me think you dont have proper DNS resolution, maybe
try pinging 4.2.2.2 or some other ipaddress.

The dns servers arent properly set which do not resolve www.yahoo.com to the ip address.
Edit /etc/resolv.conf and add nameserver dns.ip

Sample Config, which should work for you
Quote:
nameserver 208.67.220.220
nameserver 208.67.200.200

Question More information

Thanks, for the help you have provided. A few things I have found:
1. By editing the /etc/resolv.conf allows me to ping the net but mozilla still returns an error and can not access the internet.
2. Network Manager Applet 0.7.0 says I am not connected. Across the top of the window is a icon of two blue terminals with a red "X" at the bottom right corner. Also when I run system updater, it says there is no connection. Where can I find configuration documentation for Network Manager?
3. Each time I restart the VM the only data in resolv.conf is 10.0.2.3.
4. Just for fun I install Fedora on a real machine and all worked without any problems. I even did not have to edit resolv.conf.
