Bridged networking non-functional

[timk6]

I just created a Debian 8 vm with NAT networking and then switched the VM config to bridged and restarted it. It's otherwise a virgin install.

I can access the VM now (with ssh) but the VM has a completely non-functional network (except that I can ssh in). It can initiate connections (to internet web sites, for e.g.) but hangs connecting to anything. Testing against a webserver I see it received a 200 OK but then hangs before starting any download. Similar problem with other protocols.

Also, there seems to be no way to send the guest a "ctrl-C" anymore, what happened to that? I can't interrupt any processes on this VM without powering it off or ssh-ing in and killing it. Pretty silly. How can I add a shortcut key to send an interrupt? There doesn't seem to be a way from Input -> Keyboard -> Keyboard Settings, which is what looks like the right place.

• So, 'ssh' works, but 'http' doesn't? Is that correct?
• What about 'ftp', 'ping', 'smtp' or other protocols?
• Any firewall rules? Host and/or guest, and/or router?
• Is bridged on wireless or wired connection?

Read the Minimum information needed for assistance. We know some things about your guest (Debian 8, 32/64-bit?), but nothing about your host. And post the 'ifconfig' output of host/guest.

I managed to solve the issue by using the virtio-net ethernet adapter for the guest. None of the others would work at all, a few seconds of operation and then nothing.
