Hey all, Can anyone give me pointers on how (or whether it''s possible) to set up a watch on an item in the xenstore from a userspace program in domU? Any help would be greatly appreciated.

Ah, ok. Thanks for the info. My basic problem is that from dom0 I''d like to be able to signal a domU to run a script without using networking. I was hoping to put a watch on an item in xenstore. Are there any good examples of doing this sort of thing using event channels from a userspace program in domU? Thanks again! ~Dave --- Vincent Hanquez <vincent@xensource.com> wrote:> On Mon, Dec 11, 2006 at 02:44:52PM -0800, David > Richardson wrote: > > Can anyone give me pointers on how (or whether > it''s > > possible) to set up a watch on an item in the > xenstore > > from a userspace program in domU?
