[Xen-devel] can dom0 modify Shadow PT of HVM domU?

["Wu Bingzheng" <wubingzheng@xxxxxxx>]

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
