Today I retried ovmf after long time from previous, I tried old fedora 20
uefi domUs and still boot correctly but trying to boot from cdrom using
boot='dc' or boot='d' don't boot from cdrom (seems didn't try) but boot from
harddisk (even with boot='d').
After booting fedora I checked the cdrom and see it correctly, the problem
seems only about boot order.
xen is build from staging git based on commit
44313ab77f3e3c5b566ea4f23b0e32bfd5eafa29 and ovmf is from debian package

If you need more informations/tests tell me and I'll post them.

Thanks for any reply and sorry for my bad english.
What has changed in your setup? I guess it's only Xen? Do you use the
same OVMF image all the time?

If the only thing changed is Xen, I would suggest you bisect the
hypervisor. There were a bunch of changes in emulation code there.
If you don't have a base line version, I will try to come up with one
for you.

Thanks for reply, I did other tests and I found that having empty harddrive boot from cdrom correctly also with omvf, the problem seems that not cosider boot option at all. I did also few tests about ovmf and if I remember good is the first time I try to boot from cdrom on domUs with harddrive not empty, other time I did it only for system install, then is probable that the is present also in older xen and ovmf versions.
