Subject: send_fake_arp lost during live migration
Date: Thu, 22 Feb 2007 14:07:27 +0000 [thread overview]
Message-ID: <45DDA39F.9030701@dcs.gla.ac.uk> (raw)
Hi,
I think that the ARP broadcast sent by send_fake_arp in netfront.c gets
lost during live migration even though it is called during migration in
backend_changed(). Therefore, the outage is aroung 2s instead of tens of
ms as expected.
I am able to see in tcpdump the ARP broadcast when domU boots, but not
when it is live migrated.
I have also noticed a strange behaviour or arping. When I arping any
host from domU it stops after sending and receiving the first probe.
Has anyone else experienced this problem?
I am using xen 3.0.3 and this is my network setup:
vif = ['mac=00:16:3E:F6:BB:01']
dhcp="off"
ip="130.209.253.132"
netmask="255.255.240.0"
gateway="130.209.240.48"
hostname="raoul"
Thank you.
Cristian
