Hello, The following patches set a sane initial MTRR state for both Dom0 and DomU PVH guests. Note that for Dom0 the host MTRR state is used, OTOH for DomU the default MTRR type is set to write-back.
This should avoid guests having to setup some kind of MTRR state in order to boot. This has been rebased on top of a couple of fixes/improvements from Jan, which are also included in the series. Thanks, Roger.
