[Lguest] [LGUEST] Basic Suspend and Resume Support

[salil kanitkar]

Addition to the previously done suspend and resume or rather Hibernation
that we had posted about, we have added a feature of Migration of entire
virtual machine over LAN.

We suspend the lguest VM as stated before and transfer the entire rootfile
using scp (speed is about 10mbps and a rootfile of 2GB) and as we have added
a new argument for resume in lguest booting command line we can resume the
userspace by booting up new lguest guest using the newly received rootfile
on the second machine. The userspace gets resumed giving the appearance of
migration of VM.The code is a shellscript file.

The checkpointing tool used is 'Cryopid'.

Should there be any other approach like the triple ctrl-Z for suspending?

The extension for migration would be 'Live migration' that we intend to do
,could you please suggest any approaches or ways.
