Hi, Keir, Looks like a global I/O bitmap defined for all HVM domains, which definitely doesn''t apply to HVM domain with VT-d support. Do you take it as a temporary step for port 80 only and expect later VT-d patch to change that? :-) Thanks, Kevin _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

The main thing was to move away from per-vcpu bitmaps (which was totally unnecessary) and also to unify bitmap handling into common hvm code. We can beef up the support as needed in future. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
