The main problem is that this domain needs to have privileges > to access other domains memory (otherwise the backend driver doesn't work). > I don't know of a way to specify this in a domain config. this can currently be achieved (in a really sleazy way) by adding a pci= line in the non-0 domain's config, and just handing it a device that it doesn't have drivers for and so won't touch. this is clearly not the, um, ideal approach to elevating privilege, but it may get you going until the tools catch up. ;) hth, a. ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
