I did migration test on RHEL5.10 with RHEL7.0, it got 7-15 packet lost during the migration. Also I have try to set the net.ipv4.conf.{all,default,IFACE}.arp_notify sysctl to 1 in the guest and did migration test again but the network still lost about 7-15 packet. Is it acceptable with lost 7-15 packet? Host: kernel-xen-2.6.18-380.el5 Guest: kernel-3.10.0-86.el7 Here are the details: 1. Start nfs in System A and mount the nfs to System B. #mount $SystemA_ip:/var/lib/xen/images /var/lib/xen/images 2. Edit "/etc/xen/xend-config.sxp" on two machines as following: (xend-relocation-server yes) (xend-relocation-port 8002) (xend-relocation-address '') (xend-relocation-hosts-allow '') # service xend restart 3. Do migration operations System A to System B: --- 10.66.85.222 ping statistics --- 23 packets transmitted, 16 received, 30% packet loss, time 24355ms rtt min/avg/max/mdev = 0.552/2.155/18.863/4.389 ms System B to System A: --- 10.66.85.222 ping statistics --- 25 packets transmitted, 15 received, 40% packet loss, time 27388ms rtt min/avg/max/mdev = 0.000/2.422/10.114/3.199 ms System A to System B: --- 10.66.85.222 ping statistics --- 20 packets transmitted, 14 received, 30% packet loss, time 22685ms System B to System A: --- 10.66.85.222 ping statistics --- 26 packets transmitted, 16 received, 38% packet loss, time 27730ms rtt min/avg/max/mdev = 0.000/4.141/49.098/11.691 ms

Yeah, that's fine. Thanks.
Because 7-15 packet lost is acceptable, so change status to VERIFIED.
