First question: If domA grant access permission of a page to DomB, and domB remapped this page but then it crashes or failed to end mapping. Now domA wants to end page granting, what will happen? Is there any way for page owner to actively stop other VM's mapping? Second question: If domA grant read-only permission on a page to domB, but domB tries to write some data to this page. What will happen? General Memory Protection? These two questions are very important to my research. Can someone give me a answer to direct me somewhere so that I can read more details about grant table. Many thanks! -lily _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
