Does it attempt to solve both problems? No. There has been no discussion of storing suspended domains. For the moment, i think it's probably best to design the store to contain runtime state for the currently executing set of VMs on the physical host. So records in the store are persistent across daemon restarts, and dom0 restarts. I don't think any of use really imagine the store as being a very complicated bit of code at all. The bit of design that needs a little more thought is how things like device driver setup should look with the new control tools. This isn't necessarily terrible -- but changing e.g. device channel negotiation at driver setup is going to be a lot less work this round (with three split drivers) than it is going to be if we need yet another set of control tools for Xen 4. ;) a. ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
