From d293dac8f30e46f0cb66fbcce2977d73d56fe103 Mon Sep 17 00:00:00 2001 From: Yuanhan Liu Date: Fri, 29 Jan 2016 12:58:00 +0800 Subject: [PATCH] vhost: claim support of guest announce It's actually a feature already enabled in Linux kernel (since v3.5). What we need to do is simply to claim that we support such feature, and nothing else. With that, the guest will send an ARP message after live migration to notify the switches about the new location of migrated VM.
