Still use emualted disk and network and xen pv network is unable to
start for code 10 error (from windows devices manager). (see also
screenshot in attachment)

In attachment full qemu log with xen_platform trace.

That means you have not rebooted to allow the emulated device to be
unplugged. Other versions of Windows will prompt for the reboot but
Microsoft broke the class installer in Windows 10 so it won't.

Thanks for reply.
I already did a windows reboot after pv install but after doing another
seem ok.
Remain the dubt with ahci, I saw both emulated and pv ok in windows
devices manager and I not understand if a changes is needed for ahci
qemu side as Stefano Stabellini told.
Can you take a look to this new qemu log please? Is ok or with ahci disk
is not pv correctly?

The log shows:

xen_platform_log xen platform: XENVBD|__ReadDiskInfo:Target[0] : 104857600 
sectors of 512 bytes (512)
xen_platform_log xen platform: XENVBD|__ReadDiskInfo:Target[0] : 50 GB 
(00000000)
xen_platform_log xen platform: XENVBD|FrontendReadDiskInfo:Target[0] : 
Features: BARRIER FLUSH DISCARD
xen_platform_log xen platform: XENVBD|FrontendReadDiskInfo:Target[0] : DISCARD 
0/1000
xen_platform_log xen platform: XENVBD|FrontendReadFeatures:Target[0] :

xen_platform_log xen platform: XENVBD|FrontendReadFeatures:Target[0] : INDIRECT 
100
xen_platform_log xen platform: XENVBD|__FrontendSetState:Target[0] : in state 
CONNECTED
xen_platform_log xen platform: XENVBD|__FrontendSetState:Target[0] : in state 
ENABLED
xen_platform_log xen platform: XENVBD|PdoCreate:Target[0] : Created (PV)

That last line says you have a functioning PV disk.

   Paul

Thanks for your reply.
So with ahci even if Windows sees also emulated one in device manager should properly use the pv?


If you need more information and/or test tell me and I'l post them.

Thanks for any reply and sorry for my bad english.
