[Xen-devel] Question about windows domU long boot time in xen and help for update libxl virtio patch (for a test)

In latest years hvm domUs support and performance was increased but windows boot time is still too long. I tried out all sort of combinations (without pv, with old gplpv and new winpv, with vnc, spice or without both, with different vgas and many other options) with same result: strange long boot time (before arrive to user login). On kvm (trying with same qemu/seabios versions, qdisk with raw ecc...) instead for example the boot time is faster and similar to the phisical pc one with same vcpu ram ecc as assigned. Is there something that need to be improved/fixed in windows pv drivers or xen?

I tried to narrow down my search trying with virtio disk on xen but I was unable to have libxl patch working.
I taken very old Wei Liu patch from here:

And I tried to adapt it but there is something that I not understand and causing the build fails: libxl.c:2339:32: error: LIBXL__DEVICE_KIND_VIRTIO undeclared (first use in this function)

Here the path I updated and tried failing, I did only disks part (nic need only model change in xl.cfg FWIK):

Can someone help me to complete/fix it please?

Thanks for any reply and sorry for my bad english.
