I take it you're referring to this: #ifdef CONFIG_STUBDOM if (logdirty_bitmap != NULL) xc_hvm_modified_memory(xc_handle, domid, _addr >> TARGET_PAGE_BITS, ((_addr + _len + TARGET_PAGE_SIZE - 1) >> TARGET_PAGE_BITS) - (_addr >> TARGET_PAGE_BITS)); #endif Yosuke Iwamatsu: is this not working for you then ? It's possible that I've broken it somehow. Ian. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
