I have an important question about XEN's migation operation related to the XEN block and network back/front drivers. If I migrate a domain from one machine to another in the middle of heavy disk/network activity, what happnens to the back/front end XEN drivers? (I see they have suspend/resume operations but I don't believe they are being used) I see that the front end drivers are passing machine addresses to the back-end drivers - are these pointers somehow still valid when a domain is moved to another machine? Shouldn't the drivers wait until there is no I/O activity before being migrated?
Thanks,
Eric
