lijin 2017-06-27 03:33:03 UTC Doc Text Feature: VIRTIO_NET_F_GUEST_ANNOUNCE support - ipv4

Reason: There is high packet loss when live migrating windows guests.
virtio-win needs a feature to announce its presence on the new network links since the hypervisor does not have the knowledge of the guest network configuration so some packets could be missed in case of vlan usage.

Result: On control interrupt if the bit VIRTIO_NET_S_ANNOUNCE of status is set
the driver should send gratuitous arp packet. In order to send the packet from the driver, it should have the IPV4 address/es that was assigned to it.
The current implementation creates an Arp packet for each IPV4 that was assigned to the interface and it sends the packet upon receiving VIRTIO_NET_S_ANNOUNCE.

The current implementation creates an Arp packet for each IPV4 that was assigned to the interface and it sends the packet upon receiving VIRTIO_NET_S_ANNOUNCE.
The virtio-win driver now supports the VIRTIO_NET_F_GUEST_ANNOUNCE feature, which, if configured, ensures that ARP packets are recognized by the network when performing live migration of Windows guests. As a result, packet loss during the migration is significantly decreased.
