Hi,

I am using Xen live migration to migrate an ssh logined VM.

I found that sometimes the ssh session was alive after migration, sometimes not.

It seems if the ssh sesstion does not output anything, the sesstion can be held, otherwise it can not.

Can anyone identify the problem for me? How can a tcp link be kepted alive after migration?

Thanks,

Shawn
