Many thanks to Simon for his trouble shooting on live migration. I have now started testing remus according to the remus link http://nss.cs.ubc.ca/remus/doc.html

1) Remus in its simplest mode (--no-net option), without disk replication or network protection, is now working good.

2) When we add the network buffering protection (remove the --no-net option), remus gives the error as follows:

modprobe -q ifb

modprobe -q imq

Traceback (most recent call last):
  File "/usr/bin/remus", line 210, in <module>
  File "/usr/bin/remus", line 119, in run
  File "/usr/local/lib/python2.6/dist-packages/xen/remus/device.py", line 272, in __init__
    self.pool = Netbufpool(selectnetbuf())
  File "/usr/local/lib/python2.6/dist-packages/xen/remus/device.py", line 174, in selectnetbuf
    raise BufferedNICException('no net buffer available')
xen.remus.device.BufferedNICException: no net buffer available
Exception AttributeError: "'BufferedNIC' object has no attribute 'bufdev'" in <bound method BufferedNIC.__del__ of <xen.remus.device.BufferedNIC object at 0xd9dd90>> ignored

I googled, but find little useful info. Could anyone know my problem?
