I decided to come at this from a different angle and acquired a "Centrina???" Intel white-box 64 bit Core2 Duo system with Intel VT technology. This should give me "full virtualization" capability for Xen. However, while the installer of the ix_64 package completes without problem (si long as the acpi=off switch is provided) I get an error when system first boots after the install followed by a halt I see this message: BIOS BUG No explicit IRQ entires. Using default mptable (tell hw vendor) I get a second message relating to IRQ9 telling me to boot with irqpoll. Does anyone here know what I need to do to get past this?
