FYI
I got an Intel DQ43AP board and tried enabling VT-d,
but had a same problem that described below.
http://lists.xensource.com/archives/cgi-bin/extract-mesg.cgi?a=xen-devel&m=2009-06&i=8686c3cd0906300041r3b59d2c9i7a9d7c6705aa1ed4%40mail.gmail.com
> (XEN) clear_fault_bits: CAP_REG=0xffffffffffffffff
Chasing the thread, I figured out that BIOS on the board looks
have some problems around VT-d feature.
- already updated BIOS to recent version (ver 0027, 2009-7-28).
http://downloadcenter.intel.com/Filter_Results.aspx?strOSs=All&strTypes=All&ProductID=3119
- VT-d is enabled in BIOS configuration.
- tried not only xen 3.4.0 but also xen-unstable that I got a few
hours ago, but got same result.
I expect to wait for BIOS updates, although let me know what I can do
if anyone have any ideas.
