[Xen-devel] Re: Live vm migration broken in latest xen-unstable

[John Byrne <john.l.byrne@xxxxxx>]

I have live migration working fine on x86-64 with changeset 11433; 
however, the reason I thought it was broken is that it currently seems 
to need a lot more memory. Using SuSE's latest xenpreview bits I could 
migrate a 3GB guest between two machines (6GB and 4GB). With the new 
bits, a 2GB guest could be migrated off the 6GB machine, but the 4GB 
machine could not migrate it back. I currently have the VM set to 1.5GB 
and it ping-pongs fine. Any idea why so much extra memory seems to be 
required?
