[Xen-devel] Question on Lazy VM Restore

[Prateek Sharma <prateeks@xxxxxxxxxxxx>]

Hello all,
	I was wondering if there is an existing mechanism in Xen for 
restoring a saved/checkpointed VM lazily. By that, I mean that the pages 
of the VM should be mapped only on access.
	Currently, restoring a VM from a snapshot seems to take a long 
time [~20 seconds for 2 GB].
	Assuming that there is no lazy-restore functionality, what would 
be a good way to implement this? Using parts of Xen-paging? Snowflock? 
Something else?
Thanks!
