I think this is not a bug. pls note ...

Ack'd, even if the limitations are not fully understood:-/

or you
can set "pci-passthrough-strict-check no" in /etc/xen/xend-config.sxp and
restart xend to loose the check in xend, but in this way you should be aware
of potential issues (e.g. assigned device doesn't work).

sure.  would it not be reasonable to have a similar config-file option
in xen 3.x -- with similar warnings etc -- as is done in 4.x? if all
that's required for a workaround is a patch similar to that above ...

thanks
The option was introduced by changeset 20179. It's small. It can be back ported to Xen 3.x if need.

Regards,
Weidong
