I'm in the middle of a (re-)install on a domU and looking for quick replies as too which GPLPV to use on a Windows 2008 Server install. Windows 32bit Xen/Centos 64bit (x86_64) The question is regarding whether the driver to load into Windows is for "itself" (32bit) or the underlying hypervisor (x86_64) as in: ==== There is now one download per platform/architecture, named as follows: * gplpv_<chk/fre>_<platform>_<arch>_<version>.msi * chk is a 'checked' build which contains debug info (please use these if you want any assistance in fixing bugs) * fre is a 'free' build which contains no debug info * platform is 'wxp' for XP, 'wnet' for 2003, and 'wlh' for Vista/2008 * arch is 'x86' for 32 bit and 'AMD64' for 64 bits ==== Is the architecture ('<arch>') x86 (for the Windows domU 32bit architecture) or x86_64 (for the arch version of Xen running)? I'm having a gray moment.
