Hi, there is another variable to be taken into account: the IP version. Here is how I plan to address it.
First, rename spice_addr to spice_bind. --spice_bind argument will have the following form: address[,ip_version]. If the address is an IP address, including ANY or LOOPBACK, the ip_version is useless. If the address is a network interface name, the IP version will be used to choose the protocol in case of interfaces working with both IPv4 and IPv6 addresses. If the IP version is not specified, Ganeti will try to infer it. If it is not possible (IPv4 and IPv6 interfaces), it will default to 4. Any inconsistencies will result in an error. Opinions? Thanks, Andrea
