I am trying to migrate virtual machines within the cloud using virsh migrate command. I could successfully implement it but when i wanted to know the method used to do live migration. I tried to interpret the code. I also saw that they are setting a flag initially if it is live migration and then assigning 1 to variable live. and i also could find that xenDomainMigratePrepare is calling xend_op which in turn is calling xend_op_ext. But i could'n understand the method of migration. Can you please explain the logic? As a thought, in case you don't get a timely answer here, have you also asked on the Eucalyptus forums? http://open.eucalyptus.com/forum Just thinking there will be more people who know about how Eucalyptus does things there. :) Regards and best wishes, Justin Clift -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
