Hello.

I'm a new xen user. I'm learning how works the xen hypervisor that I have installed on ubuntu 20.04 with the command : apt install xen-hypervisor. I want to boot the phisycal installation of windows 10 x64 bit that I have on /dev/sdb,which belong to these partitions :

Disk /dev/sdb: 465,78 GiB, 500107862016 bytes, 976773168 sectors
Disk model: Samsung SSD 860
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: 98970711-6557-43CB-86D8-14B5F013ECFD

Dispositivo     Start      Fine   Settori   Size Tipo
/dev/sdb1          34    262177    262144   128M Microsoft reserved
/dev/sdb2      264192   1286143   1021952   499M Windows recovery environment
/dev/sdb3     1286144   1488895    202752    99M EFI System
/dev/sdb4     1488896 975591423 974102528 464,5G Microsoft basic data
/dev/sdb5   975591424 976773119   1181696   577M Windows recovery environment

this is the cfg file that I'm using :

builder = 'hvm'
bios='ovmf'
vif = [ 'type=ioemu, bridge=xenbr0' ]
memory = 8192
name = "windows-10" # domain prefix name
disk = [ 'phy:/dev/sdb,ioemu:sdb,w' ]
boot = "c"
vncconsole=1
vfb = [ 'type=vnc,vnclisten=127.0.0.1,vncdisplay=1' ]
vcpus = 6 # number of cpu's to assign
stdvga = 0
serial = 'pty'
usbdevice = 'tablet' # Required for USB mouse
_on_poweroff_ = 'destroy'
on_reboot   = 'destroy'
on_crash    = 'preserve'

device_model_args_hvm = [
  # Debug OVMF
  '-chardev', 'file,id=debugcon,path=/etc/xen/ovmf.log,',
  '-device', 'isa-debugcon,iobase=0x402,chardev=debugcon',
]

I run this script :

#!/bin/bash

sudo /etc/init.d/xencommons start
sudo /etc/init.d/xendomains start
sudo /etc/init.d/xen-watchdog start
sudo /etc/init.d/xendriverdomain start
xl create xenwin.cfg

but vncviewer tells that "guest has not initialized the display (yet)" and it is freezed there forever. some help ?
