'k, that didn't help any … still get told no long mode, use a 32bit distro … showvminfo shows:

Reading through the section on Hardware vs Software Virtualization, apparently VT-X has to be enabled for 64bit guests … now, on the server I'm using, looking at dmesg for ny CPU Features:

I don't see VTX in there … *should* I?   Is this a case of, unbeknownst to me, it isn't enabled in the BIOS?  This is a remote server, so a quick reboot / check isn't the easiest to do, so would alike to confirm before I go down that route … can someone that does have 64bit guests working check their CPU Features and let me know if I am missing that Feature here? :(

Thx …
