I am sure this not just a 1.0.1 problem and there appears to be a bugzilla report on it: https://bugzilla.redhat.com/show_bug.cgi?id=869625 Given a F17 host and a F18 host, there is significantly different behavior when running a guest (in my case a F18 guest). On F18, I cannot ssh or scp to the host let alone any other system. Also, although DHCPv6 is working and I am getting an IPv6 DHCP address assigned. Also, I can use firefox to access an Internet website. Oh, and host returns no response. I am not sure what is wrong but I hope this is easy to fix. Gene
