Hi! I''ve got a motherboard (Gigabyte GA-G33-DS3R) where the Ethernet port has been broken. I''ll buy a new motherboard, but wants to keep all my other equipment (CPU, Memory, TV-cards etc). The requirements/wishes on the new motherboard are 2 Ethernet ports and 2 PCI slots. It would also be good if it would support VT-d. I''ve found two boards that would fulfill my requirements; Gigabyte GA-X48-DS5, Gigabyte GA-X48-DS4 According to the VTdHowTo (http://wiki.xensource.com/xenwiki/VTdHowTo) X48 chipset supports VT-d. But not all manufactures have enabled it. Does anyone know if VT-d is enabled for the motherboards above (or any other motherboard that would support my requirements)? /Andreas _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I had a case open with Gigabyte some time ago asking for vt-d support on
X38 and they told me that vt-d support is not planned for any of their
boards, so I''d suggest to stay away from them.
Asus might be even worse, allowing you to enable vt-d in the BIOS but
then telling you it''s unsupported when it doesn''t work.
If you really need vt-d I''d suggest to go with Intel boards for now...
Best regards,
Christian

Do you or anyone else on the list know how support for VT-d is on Supermicro boards? I have seen the options listed in the motherboard manuals for some of their boards but haven''t actually tried myself. I have actually been contemplating buying a Supermicro C2SMB-Q. Thanks if your or anyone else has some info.

So if you need gplpv drivers and pci passthrough you can have stability or multiple cpu''s, but not both, yet, I''ve been too busy to work on this problem until yesterday but I''ve now emailed James about it so with luck the gplpv drivers will work with unstable soon, once they do I will try passthrough again and report back my results.
