The most likely problem here is that the libvirt args have acpi turned
off. Add the '<acpi/>'  element within <features> in the libvirt XML.
That should get rid of the '-no-acpi' flag libvirt added.

One more likely problem here is the different of 'cirrus' vs 'std'.
Windows hates having its graphics card changed behind its back :-)
Try changing the libvirt XML for <video> to 'vga' instead of 'cirrus'.
That will make libvirt spawn QEMU with '-vga std' which matches your
script.

That's not a problem - libvirt passes the file descriptor to QEMU when
it starts it.
