[Xen-devel] msitranslate: question about qemu-upstream and pv support

I noticed that the patches for msitranslate do not seem to have made it
into qemu-upstream. The logic still exists in
xen/drivers/passthrough/io.c, though documentation suggests MSI-INTx
translation is only implemented for HVM guests.

Based on the disabling of MSI-INTx by default, it seems safe to assume
that MSI translation is only supported under qemu-xen-traditional, and
only for HVM guests. Is this correct?

I don't see any mention of this on this wiki page:
