Finally I've made it! It seems that I am getting into this issue only if it goes via VDE2 switch. I've launched both guests via "Tap to Bridge" interface and had no issues at all. I guess it is a bit of a good news here... I have attached my net interfaces config file and a guest launcher for

In that case maybe you should close it for a while? Would it be possible to reopen it later? I'll try to reinstall my host OS and see how it goes... Besides I am waiting till Fedora 17 gets into final state (might take another month) which I am planning to install in parallel on my host. I know
