Not a regression. Same problem with clean installation of Fedora-Live-Workstation-x86_64-23-10.iso (final) as a guest.

On the > host, this works fine. I suppose the virtual interface is configured to do IPv4 NAT and masquerading but doesn't provide IPv6 connectivity to the guest; NM tries to configure both IPv4 and IPv6 on the guest but only the first succeeds. This looks like a request for enhancement on libvirt side, so I'm reassigning this bug to that component. I assume this is just using the 'default' virtual network/virbr0? If so, it doesn't have any ipv6 config, it's just ipv4 nat, so ipv6 in the VM doesn't work out of the box. Unfortunately there really isn't any easy out of the box IPv6 option for VMs unless you manually bridge your host interface |
Created attachment 1141066 [details] journal.log Description of problem: Google search for ipv6 tests, and run any of them, they all fail when Fedora 24 Alpha is run from within a libvirt VM. On the host, this works fine. Version-Release number of selected component (if applicable): NetworkManager-1.2.0-0.6.beta2.fc24.x86_64 How reproducible: Always when in VM, never on baremetal. Steps to Reproduce: 1. 2. 3. Actual results: No IPv6 address is available. Expected results: Seems like IPv6 should be supported in guests when the host has IPV6 connectivity.
