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 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
