Thanks for the advice, I tried it:
https://github.com/Fantu/Xen/commits/rebase/m2r-testing-4.6
I installed W10 pro 64 bit with ide disk, installed the win pv drivers
and after changed to xvdX instead hdX, is the only change needed, right?
Initial boot is ok (ovmf part about pv disks seems ok) but windows boot
fails with problem with pv drivers.
In attachment full qemu log with xen_platform trace and domU's xl cfg.
Someone have windows domUs with ovmf and pv disks only working? If yes
can tell me the difference to understand what can be the problem please?

Thanks for the advice, I tried it:
https://github.com/Fantu/Xen/commits/rebase/m2r-testing-4.6
I installed W10 pro 64 bit with ide disk, installed the win pv drivers
and after changed to xvdX instead hdX, is the only change needed, right?
Initial boot is ok (ovmf part about pv disks seems ok) but windows boot
fails with problem with pv drivers.
In attachment full qemu log with xen_platform trace and domU's xl cfg.
Someone have windows domUs with ovmf and pv disks only working? If yes
can tell me the difference to understand what can be the problem please?
