I have tried this on two different motherboards and neither works: 1) Win XP running on an Intel 945 mobo with a Pent D 940 which supposedly has VT support. 2) Ubuntu Karmic 64bit on a MSI P4M890 with a Pentium D 925 which may not have VT support. Is the claim here that you cannot virtualize 64bit w/o VT support? Certainly you seem not to need it for 32 bit guests. -- ---------------------------------------------------------------------------- Tim Daneliuk tundra@tundraware.com PGP Key: http://www.tundraware.com/PGP/
