Xen devel - Sep 2008 - How do you change XenStore permissions?

Hi,
Is there a way to change the permission for a specific path in XenStore? And
can you do that from with in a C program?
Thanks
Julian

> Is there a way to change the permission for a specific path in XenStore?
Yes, with the SET_PERMS message.

e.g. SET_PERMS (/vm/00000000-0000-0000-0000-000000000000/uuid r0 )

This will give read access to 
/vm/00000000-0000-0000-0000-000000000000/uuid to all domains.

> And can you do that from with in a C program?
Yes. Check out this page under the "API Usage Examples":

If you have any questions about how the permissions work in XenStore, 
feel free to ask (it''s a bit confusing).
