I tried with saucy and it boot but has graphic performance issue and

About windows problem it is probably due to a missed cirrus driver
on windows 7.
The only other option that I found should be try with stdvga but
seem it needs legacy vgabios from csm.
What if I try to add ovmf patches for legacybios (that seems to have
also memory patch) from this git?
Does it make sense without modification to hvmloader?
Thanks for any reply.
It's really hard to tell whether these out-of-tree patches will be of
any help for the cuurent situation.


Sorry, I try to better explain what i meant:
In my earlier mail, what I was asking is:
since the patch to OVMF to prevent it from marking the region from 0xC0000-0xFFFFF as read-only before invoking Legacy16Boot method is already present on the git I've linked, I was asking if such a patch should works without any further modification xen-side. On the other hand, if you think the patch will never work without xen modifications, I'll not test csm now but I'll wait xen change.
