Also, if you see disabled, grab the model number of your CPU and check the CPU specs to see if the CPU support I/O Virtualization. I''m not sure about AMD, but Intel''s site has very easy-to-read specs for the CPUs that tell you about the various features they support. -Nick -------- This e-mail may contain confidential and privileged material for the sole use of the intended recipient.

I don''t know - if you''re running Xen you need to use "xm dmesg" and not just "dmesg" and look for I/O virtualisation. -Nick>>> On 2013/01/22 at 08:43, lei yang <yanglei.fage-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: > On Tue, Jan 22, 2013 at 10:26 PM, Nick Couchman <Nick.Couchman-nV4p5R2ZCao@public.gmane.orgm> > wrote: >>>>> On 2013/01/21 at 19:45, lei yang <yanglei.fage-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: >>> Hi experts, >>> >>> Is there a method to check my machine support VT-d without checking >>> bios, I want use a script or tool to get this >>> >>> >>> Lei >> >> Yes...if you look at the "xm dmesg" output, you should see one of the > following lines: >> >> (XEN) I/O virtualisation enabled >> >> or >> >> (XEN) I/O virtualisation disabled >> >> >> If you see the "disabled" version of the message, check your BIOS to see if > it just needs to be turned on.
