Re: [Xen-devel] XCP PV driver

GPLPV tells windows that these SCSIOP's are supported (just returns
STATUS_SUCCESS), but they don't actually do anything. As Paul implies
there is no mechanism to pass such a message back to the actual device
(which could just be a file on disk anyway). It doesn't block anything
else from accessing the device.
Maybe you could use iSCSI in the DomU instead?

Thanks. There is no reason the XCP driver could not do the same, right?
Shared disks would still be "unsupported" but it would just work on a
single physical node.
I think the configuration is useful to train/demo/play around with
Windows configurations requiring shared disks.
Oracle RAC, Fail-over clustering to name a few.
Even a single node cluster is a valid configuration for learning.
