Gns3-gui: [VMWare] Unable to create NIO Ethernet for bridge ethernet0.vnet

[AODtorusan]

Using the latest GNS3 1.4.0 RC1, I linked up an C3745 and a vmware machine loaded with IOS XRv 5.3.0. However when attempting the start the VM, I get the following exception;

GNS3 management console.
Running GNS3 version 1.4.0rc1 on Windows (64-bit) with Python 3.4.3 Qt 5.5.1.
Copyright (c) 2006-2015 GNS3 Technologies.

=> Server error from http://127.0.0.1:8000: iosxrv-k9-demo-5.3.0: unable to create NIO Ethernet for bridge 'ethernet0.vnet'

It doesn't matter if the C3745 is started before starting the XRv image.

I am using GNS3 1.4.0 RC1 & VMWare workstation 11 in Windows 10 x64.

Hum, looks like a right issue. Make sure you have installed Winpcap and do the following:

Start cmd.exe as an administrator.
Type sc config npf start= auto
Reboot your computer.
Try again.

Thanks,

That fixed it.

Come to think of if, I don't remember if I rebooted after installing winpcap. Perhaps the service is only first started after a reboot.

Thanks for the feedback

I also came across this issue when linking a winxp image and l2iou switch.

Jeremy's fix resolved my issue - thanks.

Is this a possible bug?

Jeremy,

Do you have a solution to this for Linux?

[noplay]

@ishouse I think it's a permissions issue. Are you running GNS3 under the same user as VMware?

[grossmj]

On Linux, make sure the ubridge command has the right capabilities:

$ which ubridge
/usr/local/bin/ubridge
$ getcap /usr/local/bin/ubridge
/usr/local/bin/ubridge = cap_net_admin,cap_net_raw+ep

If the right capabilities aren't set then type the following:

sudo setcap cap_net_admin,cap_net_raw=ep /usr/local/bin/ubridge

grossmj,
thx for advice!!!
I use the GNS3 version 1.4.5
Executed command "sc config npf start= auto" helped to resolve the error message "unable to create NIO Ethernet for bridge 'ethernet0.vnet".
