I added the following: HYPERVISOR_shared_info->arch.pfn_to_mfn_frame_list = (unsigned long)xen_phys_machine; HYPERVISOR_shared_info->arch.mfn_to_pfn_start = (unsigned long)xen_machine_phys; xen_phys_machine is start_info->mfn_list an xen_machine_phys is (1008 << 22) I'm now seeing: (XEN) (file=/t/niners/users/xen/xen-2.0-testing.bk/xen/include/asm/mm.h, line=157) Error pfn 00073000: ed=fc5f8040, sd=00000000, caf=00000000, taf=0000000a I know that comes from this: if ( unlikely((x & PGC_count_mask) == 0) || /* Not allocated? */ unlikely((nx & PGC_count_mask) == 0) || /* Count overflow? */ unlikely(d != domain) ) /* Wrong owner? */ { DPRINTK("Error pfn %08lx: ed=%p, sd=%p, caf=%08x, taf=%08x\n", page_to_pfn(page), domain, d, x, page->u.inuse.type_info); return 0; } But maybe you'll know off the top of your head what is wrong? -Kip > > > I tried 'xm save 0 foo' - which I'm not sure should be allowed - and > > saw the following: > > There should be a safety catch on this.
