Capture on VirtualBox VM doesn't work anymore

[ghost]

GNS3 version 1.3.0rc1, OS: Linux, Debian 8

Starting capture on a VirtualBox VM doesn't work anymore, on 1.3.0beta2 it was working.

GNS3 Console output:

What is the network configuration for your VM? (how many adapters etc.)

Thanks,

Here my VirtualBox configuration:

And here my GNS3 project:

And that's my ifconfig:

I tried with a simpler configuration, a VirtualBox VM with one port. Then it works. If I try with 4 ports on the VM and connect Ethernet0, it also works. But if I leave Ethernet0 empty and connect Ethernet1., then I get this error.

It seems, that the empty Etthernet0 creates this problem.

@ehlers thanks a lot, you have done all the debugging for me ;)

Unfortunately I could not fix it before we release RC2. However, I will definitely have it fixed soon, ready for 1.3 final.

Cheers,

@ehlers

This is fixed. The issue was on the client side. Let me know if you find other issues.

Thanks :)
