If possible, could you provide dmidecode information (type "dmidecode") for further verification? I know that some vendors disabled SVM feature in BIOS last year. But this was pretty rare.

If not, is trapping the #GP on wrmsr(EFER) a good way to do it? -- Do not meddle in the internals of kernels, for they are subtle and quick to panic. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
