Hello,
Your problem is probably caused by using different interfaces on the two
hosts. You should create bond0 on both of them (even though on Host-A it
would contain only one interface - eth1). That should help.

Here is the scenario: 0. OS : RHEL5.4 86_64 1. Host-A. Port eth1 , it is trunked with three subnets xxx.xx.15.xxx xxx.xx.16.xxx xxx.xx.17.xxx Guest created on 15, 16 ,17 subnets. Gust15-A created on subnet 15 Gust16-A created on subnet 16 Gust17-A created on subnet 17 2. Host-B. Port eth0 and eth1 are bonded to bond0 Bond0 is trunked, with three subnets. xxx.xx.15.xxx xxx.xx.16.xxx xxx.xx.17.xxx Guest created on 15, 16 ,17 subnets. Gust15-B created on subnet 15 Gust16-B created on subnet 16 Gust17-B created on subnet 17 I have used the mode option in /etc/modprobe.conf as options bond0 mode=1 miimon=100 , As because mode=4 did not work, It seems the link aggregation is not properly set or something else. As the switch configuration is the part of different team, I can't explain it clearly here. But with mode=1 , it is working at this stage. 3. I am trying to live migrate Guest15-A and other guests to Host-b. Migration is ok. But,there is 5 munites delay. The guests are pingable only after 4/5 munites from different network after migration. Can anyone please advice , where to check? Do you think it is the switch configuration issues? If server side configuration issue then I can do it. If it is switch side issues , please give me the pointers or advice , so that I can discuss with the network team. If more explanation is needed , please let me know. Thanks in advance.
