This might just be a wording issue, but, the problem of running paravirtualized windows inside of xen is not a driver issue. It's a kernel issue, which can only be solved if you have the source code of the guest kernel, and you can modify it specifically for paravirtualization. So - maybe - what you're saying is that citrix & commercial xen are able to optimize drivers (similar to VMWare Tools, etc) so the virtual machine performs well in fully virtualized mode. This would reflect a confusion between the terms "fully virtualized" and "paravirtualized." Or, maybe you're saying that citrix & commercial xen were able to cooperate with MS (or hack around noncooperation) in order to create a special windows installation medium which includes a paravirtualized kernel. This would reflect a confusion of using the word "Citrix provides drivers" when you really meant "Citrix provides a kernel." _______________________________________________ Tech mailing list [email protected] http://lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
