Comment 11 for bug 1797715

As I had too much network interfaces, I uninstalled the lxc package which I didn't use anyway. Then I removed the recently created network to have everything as simple as possible. As this didn't help at all I configured the IPv4 address statically (in the guest). I must have screwed something up the last time, because after I did this, I was able to ping the guest vm from my host (yay). I'm now also able to ping the host from the guest vm and everything else (even hosts like 8.8.8.8 - even tracert in windows works).

BUT: only ping seems to work. I cannot resolve names inside my guest, no matter which DNS server I configure. I also tried opening a webpage via IP in my local net - this doesn't work either. I have no idea what could cause everything but ICPM working...
