I have setup a kvm win7 guest on a debian host. It's been up and running for a while now, but I had not done much with it. What I had done (for sure) was to download
Today I wanted to try and let putty access the host so I had to update the firewall rules. After that I had no internet connection from the guest anymore. Reverting the changes did not help either. So I wonder why I do not have Internet access from the guest anymore. I honestly can not figure out why.
I append here the following info that will most probably be of interest:
current iptable rules: http://pastebin.com/pTnfs5sr
kvm guest xml: http://pastebin.com/U0GhW0px
qemu cmd that runs the guest: http://pastebin.com/htZ4R0FE
ifconfig : http://pastebin.com/uGVN29VZ
Ifconfig shows 2 virtual interfaces:
virbr0 which I expect and
vnet0 which I do not know how it is setup and why. It does get destroyed and reappears along with
virbr0 everytime I run
virst net-destroy default and start it again.
thank you in advance for your help.
EDIT: appending the kernel routing table as well:
