To my understanding, you set ifname to prefix xentap instead of tap
for type LIBXL_NIC_TYPE_IOEMU which is for hvmdomain.  So please read
my comments below related to tools/python/xen/xend/image.py

The above shouldn't it be:

vifname = "xentap-" + vifname

For your libxl related is:

ifname = libxl__sprintf(gc, "xentap-%s", vifs[i].ifname);

Sorry if my thinking is wrong please correct me.

Thanks.

Kindest regards,
