As in the vmware vmotion? No, you can't migrate them to other harware with the vserver tools. The trouble is that vserver works by segregating the host kernel into security contexts and then running the "guest" applications within this security context. I'm not aware of any way to migrate processes from one linux box to another. So they are held hostage to the host more or less. Of course the "boot" times are on the order of 10 seconds max. So if you wanted to build a network storage system to host the guest OS, and you shut down one guest you could crank it up on the other side with only 10-15 seconds downtime. So not as slick and polished as vmware, but for those on a bit more of a budget, I think we could avoid the cost of the polish for the increased productive utilization of our current hardware. Oh, and with the reduced amount of "virtual" hardware, our backup server is now able store at almost double the speed it had been under vmware. Since the storage is out gigabit network, same switch, to the same SATA drives running via AoE, the only thing that changed was getting vmware out of the link. Went from 12-15meg/sec storage to 28meg/sec. -- Steven Critchfield [email protected] --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "NLUG" group.
