xen discuss - Sep 2009 - Does xvm support intel vmdq?

Does osol and xvm support the virtualisation goodies on Intel''s 1gb and
10gb NICs, such as VMDq?  If so, does it make much of a difference to
performance and VM density?

Thanks,

M.

Some VMDQ features are used by the Solaris drivers to implement VNICs  
efficiently. This directly benefits the existing xVM implementation.

The VMDQ features which allow a part of the NIC hardware to be  
directly accessed by a guest domain are not yet supported with xVM.  
Providing such functionality is part of our PCI SR-IOV project which  
is active at the moment but doesn''t yet have a confirmed target Nevada
build.
