Hi all, Can Xen hypervisor modify HVM domU's Shadow page table, under the dom0's context, like trapped from dom0's hypercall? I think it have to call 2 functions at least: guest_walk_tables() and flush_tlb_all(). Can these 2 functions called in dom0's context? In my test, if hypervisor tries to modify HVM's shadow page table, it will bring down the whole system. I am not sure what's the reason. Thanks, Wu 没有广告的终身免费邮箱,www.yeah.net _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
