Thanks Stephan.  I did what you suggested and NFS boot + live migration worked flawlessly. I was under the impression that since during boot we use the kernel and initrd in /boot directory of the local machine, and not the one on the server, module support should work fine through initrd. Apparently, initrd is only used for certain modules at the initial stage of boot?

For those who may come across this thread later to setup NFS + live migration, I had to change /etc/exports from having the option all_squash to no_root_squash; yes silly! :)

How do you expect to get ROOT NFS working if your NFS support is only
a module and must be loaded from the root filesystem which you want to
have via NFS? ;-)
To get ROOT NFS working you need everything for this situation static in
the kernel. So you have to say <*> (yes) for „NFS file system support".
Then you should get the new option for CONFIG_ROOT_NFS.

Your network drivers must be in the kernel as well including IP support.

Shade and sweet water!
