Guest Networking Unavailable

[jmace]

I have grown very fond of PM over the past couple months working with it in a testing environment. When I first installed it networking was working fine, however, I tried to create another bridge, on my eth1 nic, but ended up deleting it. After that, my bridged, vmbr0, network stopped connecting to the Internet. Besides not being able to get on to the Internet from many of my virtual machines, and my virtual machines cannot talk to each other on either bridged or NAT mode no matter which network adapter type I use (RealTec, Intel, or VirtIO).


Any help you could provide would be greatly appreciated.


My PM server is connected to a wireless extender with a static internal IP (192.168.1.99), Mask (255.255.255.0), Gateway and DNS (192.168.1.1). The extender is then connected to the base wireless router in DHCP mode IP (192.168.1.1), Mask (255.255.255.0), Gateway and DNS (192.168.1.1).


My /etc/network/interfaces file looks like this:

auto lo
iface lo inet loopback


auto eth0
iface eth0 inet manual


iface eth1 inet manual


auto vmbr0
iface vmbr0 inet static
        address  192.168.1.100
        netmask  255.255.255.0
        gateway  192.168.1.1
        bridge_ports eth0
        bridge_stp off
        bridge_fd 0

When I run a ifconfig, however, I get a couple of other "interfaces" that I don't quite understand as I have never set them. The output is as follows:

I solved it!

It was a Windows issue, surprise surprise. When dropping and adding network adapters Windows didn't clear out the registry values for the old interface cards. Therefore, this is what I had to do:

1) Open a command window with elevated privileges (Start -> Right-click "Command Prompt", select [COLOR=#008000][B]"Run as Administrator"[/B][/COLOR]) <-- This is key #1


2) In the command window, execute the following commands:


[B]SET DEVMGR_SHOW_NONPRESENT_DEVICES=1[/B]


[B]START DEVMGMT.MSC[/B]


The second command starts the Device Manager. It MUST be started from the elevated-privilege command window for this procedure to work. <-- This is key #2


3) In Device Manager, click the VIEW menu item and select "Show hidden devices".


This should show any hidden devices. For network adapters, expand the network adapters node. Right-Click any device you wish to remove, and click Uninstall.

I hope this helps someone else.

I still don't get all of the extra "interfaces" after running the ifconfig command, so if someone knows or can shed some light on it I would be quite thankful.

eth0 is your primary adapter. lo is your loopback adapter. tap108i0 I'm not sure about... venet0 - http://kb.parallels.com/en/647. vmbr0 is your bridge adapter.
