[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: [Xen-devel] fail to detect VT-D on Dell (optiplex 760)
HI Zhang, Andrew:
Here is my report.
I upgrade the BIOS from version A00 to A15, and the configuration
of "VT-D" is gone
(also there is no kind of virtualization setting). I'm not sure
whether this feature is removed or enabled by default.
and I haven't seen the error messages from the Xen log [1]
(XEN) ACPI: HPET id: 0x8086a701 base: 0xfed00000
...(lines between this two are gone)
(XEN) ERST table was not found

Still, is this a software issue (the BIOS?) or the hardware issue (the
mainboard) ?
Is there any documents about how to dump DMAR register?
