[libvirt] [RFC] VM which uses macvtap will not respond ping request when being migrated

A vm which uses macvtap will not respond ping request, when the vm is being migrated. I found that on the destination side the macvtap will send a IPv6 packet at the begin of migration to update the route table in switch, however VM is still on the src. In this case , what can I do to avoid VM's network disconnection Regards, Wangrui
