Bill, >> OpenVZ will have live zero downtime migration and suspend/resume some >> time next month. >> > Please clarify. Currently a migration involves: > - stopping or suspending the instance > - backing up the instance and all of its data > - creating an environment for the instance on a new machine > - transporting the data to a new machine > - installing the instance and all data > - starting the instance > If you could just briefly cover how you do each of these steps with zero > downtime... it does exactly what you wrote with some minor steps such as networking stop on source and start on destination etc. So I would detailed it like this: - freeze VPS - freeze networking - copy VPS data to destination - dump VPS - copy dump to the destination - restore VPS - unfreeze VPS - kill original VPS on source Moreover, in OpenVZ live migration allows to migrate 32bit VPSs between i686 and x86-64 Linux machines.
