How the connections work after the migration
type: item
description: Hi, I' interested in some theory... I installed OVZ, created several VMs, connected them to my local network, accessed remotely via shell and remote desktop... and live migrated these machines among 2 phisical ones. Can somebody explain me or tell where to find some material that explain how this system works? I mean how all the network level works (mainly on level 2 and 3 OSI) and how it is possible that all the connections on the VM keep on working after the migration? Which changes happens to the network to let be possible that a machine keeps it's addresses even if moved to another part of the network(and phisically to another cable!)? I hope my questions are clear enaugh... Thanks in advance Ale

description: There is this paper describing how Xen handles live migration. I imagine the issues are similar although I'm unaware of how OpenVZ tackles the problem.
