Hello; I have 2 ovirt nodes (v3.5.3, all on centos 7) with ovirt engine on separate machine, few vlans, shared storage etc. Installation is mostly standard. Virtual machines with ipv4 only works well without problems. But I have lot of issues with ipv6 on virtual machines. When I turn on virtual machine it works well (ipv4 and ipv6). But when I migrate vm than ipv6 simply stop works. Time to time works well but I don't known why .... My bridges are bonded interfaces with vlans.
Can you explain what stops working in ipv6? can you ping6 VMs on the same bridge from the migrated VM? Can you do it to VMs on the original host?
I search Internet for this issue and I found some information about issues with multicast on bridge (I try to set few parameters but without positive results ... ). Is there any solution for this IPV6 issues ? Greetings PS. Sorry for my broken English. Adam
