If we add that printk() then it's on a path triggerable by an HVM guest (via the populate_physmap hypercall, for example) and there is a potential DoS attack. The need to modify the Xen command line to enable NPT on PAE hypervisor should really be caveat enough anyway. -- Keir On 15/1/08 19:22, "Woller, Thomas" <thomas.woller@xxxxxxx> wrote: > Adding a P2M_ERROR message when startup of a PAE HVM guest, on a PAE > hypervisor exceeds the ~4Gig memory size limitation. > > Please apply to unstable (no need to add to 3.2-testing, or to 3.1.3). > > Signed-off-by: Tom Woller <thomas.woller@xxxxxxx> > > --Tom > > thomas.woller@xxxxxxx +1-512-602-0059 > AMD Corporation - Operating Systems Research Center > Austin, Texas > > _______________________________________________ > Xen-devel mailing list > Xen-devel@xxxxxxxxxxxxxxxxxxx > http://lists.xensource.com/xen-devel _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
