the printk's in hypervisor gets stored in the i/o ring buffer, it has to
be explicitly read from the userspace,
or if you have a console attached to the serial port of your machine
then all the printk's appears on the serial console automatically. For
this you have to give "console=com1,vga com1=115200,8n1" as command line
argument for the hypervisor image "xen.gz"
