>So, my assumption, based on real hardware on other platforms, that if you install Sles9 on a 64 bit VM user, it installs Sles9 as 64 bit. If you have a 31 bit user, it installs as 31 bit. But I haven't seen any documentation on how a decision is made during Sles9 installation.
Actually, If you buy SLES9, you have to specify if you want 31-bit or 64-bit. If you buy the 64-bit, you get the 31-bit version at no cost. The product comes on a set of CD's. Six CD's for 31-bit and 6 CD's for 64-bit. Pick the set of CD's you want to use. Same, I think, for the download. "A statesman is a dead politician.
