2.1.0 No 64-bit guest on 2 dual-core Opteron Win XP x64 host

From my forum posting:

I have a HP xw9400 with 2 dual-core Opteron 2200's running Win XP x64 Edition SP2 and 4 GB ram. AMD-V is enabled in bios. Had previously played with 2.0.6 and could load Ubuntu 8.10 64-bit guest. OpenSolaris 2008.11 and Solaris 10 10/08 installed but only ran as 32-bit guests. All Extended CPU settings were enabled and Ubuntu was very fast while the Solaris releases had very poor speed response.

I upgraded yesterday to 2.1.0 and Ubuntu will no longer boot - complained that there was no x64 processor present but the logfile shows 2.1.0 definitely correctly recognizes the Opterons.

I killed all VM's, uninstalled, ran a clean install of 2.1.0 and still no success. Cannot install Ubuntu 8.10 because installer says I do not have x64 enabled processor! OpenSolaris install is still 32-bit guest on boot.

Log file from last Ubuntu 8.10 install attempt are attached.

AMD-V is disabled on your host system. Better make sure it's properly enabled in your BIOS first.
