[ovirt-users] selectively disabling IPv6 on bridges

Hi, I'm looking for a way to selectively disable IPv6 on the bridge interfaces on the oVirt hosts. When oVirt creates the bridges for all logical networks on the host, it keeps the default settings for IPv6 which means all bridges get a link-local address and accept router advertisements. When a VM is created on the logical network, it can now reach the host over IPv6 (but not over IPv4 if no IP address has been assigned on the host). If it sends out a router advertisement it can even create a global IPv6 address (haven't tested this). How can I prevent this? I would like to prevent the guest from IPv6 access to the host but the guest itself still needs IPv6 access (global IPv6 addresses). Is it sufficient to create a sysctl config file that says: net.ipv6.conf.default.disable_ipv6 = 1 ? Regards, Rik -- Rik Theys System Engineer KU Leuven - Dept.
