L3110 and VT-d?

Hi, I have a Tyan Toledo q35T mainboard (S5220) and a Xeon L3110 processor. Tyan says the board supports VT-d but also the processor must be VT-d capable. Is the L3110 VT-d capable? I've searched the intel website but was not able to find any details concerning that question. I want to use this combination for virtualization (and also pci-passthrough) with xen 3.2 or 3.3 - but it doesn't work. How can I check if VT-d is enabled and working? Is there a special cpu flag for VT-d or something else that shows me that everything should be ok?

Thanks

Hi Cpt.Dogfruit,

thanks for your reply, but this spec only says that this processor support 'Intel Virtualization Technology'. That could mean a lot of things. VT-d is only a part of it and it's not guaranteed that it's included if Intel is talking about 'Intel Virtualization Technology'.

Hi, there

I remember the requirement for VT-d

1. Chipset with VT-d support.

2. Enable the VT-d in BIOS.

Thanks,

Frank

Hi frank8888,

the chipset itself should support VT-d, it's an Intel Q35 chipset. (see http://software.intel.com/en-us/forums/virtualization-software-development/topic/56802/). I have opened another request at Tyan and asked where to enable VT-d. At the bios is only a general 'Intel Virtualization Technology'-option. Don't know if this also enable VT-d.
