Re: [Xen-users] Couple questions

What will be the device driver locations in future versions of xen (i.e.
version 3.0)?

In dom0, or in dedicated driver domains, as in Xen 2.0. Some more setup code (e.g. PCI bus setup and handling) has also been moved into dom0 for Xen 3.0 - makes it easier to stay compatible with the same hardware as native Linux.

What will be the communications capabilities from virtual machine to
virtual machine and between the virtual machine and the hypervisor?

For high bandwidth transfers, shared memory communication rings and event channels are used for interdomain communications. For low bandwidth messaging and setup communications, a hierarchical "registry" called xenstore is used instead of the old style "control messages". The console will now use a separate shared memory page.

Xen <-> domain communication is via hypercalls, events (virtual IRQs) and (occasionally) shared memory.

HTH,
Mark

I apologize if this is the wrong forum for these types of questions.

Please point me in the right direction if this is the case



Thanks,

Matt
