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:
http://downloads.xen.org/Wiki/VirtioOnXen/libxl-virtio-support.patch
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):
https://github.com/Fantu/Xen/commit/783c1739df3a87689ab8c152632b249334d92f0a
Can someone help me to complete/fix it please?
Thanks for any reply and sorry for my bad english.
