The OVMF.bin file generated by the configuration / installation of XEN 4.14 does not work.

[Mario Marietto <marietto2008@xxxxxxxxx>]

Hello.

I'm trying to boot Windows 10 x64 bit guest os installed physically on the disk GPT + EFI SDC,on the sdc2 partition from the host os Ubuntu 20.10 where I have installed XEN 4.14. On sdc3 of the guest disk there is another installation of Ubuntu. Give a look below :

Disk /dev/sdc: 298,09 GiB, 320072933376 bytes, 625142448 sectors
Disk model: WDC WD3200AAJS-0
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: F2E34254-FB88-4C01-AD1E-6B1A9239D7C6

Dispositivo     Start      Fine   Settori   Size Tipo
/dev/sdc1        2048    206847    204800   100M EFI System
/dev/sdc2      206848 311425023 311218176 148,4G Microsoft basic data
/dev/sdc3   311425024 625142414 313717391 149,6G Linux filesystem

the problem that I have is that the ovmf.bin file has been generated when I have started the installation / configuration of XEN 4.14 doing :

./configure --enable-ovmf

,but for some reason it seems to be damaged and it is not able to shows correctly what's happening inside the vncviewer window,where windows 10 is loading itself. To fix it,I have also tried to rename the file OVMF_VARS.fd to ovmf.bin and I tried to boot windows 10 with that file :

cp /etc/xen/xen-4.14.0/tools/firmware/ovmf-dir-remote/Build/OvmfX64/RELEASE_GCC5/FV/OVMF_VARS.fd /etc/xen/Nazim/4.14/ovmf.bin

putting inside the xen cfg file :

bios='ovmf'

bios_override = '/etc/xen/Nazim/4.14/ovmf.bin'

but even this experiment didn't work :

anyway,the passthrough works (my monitor is turned on). what u suggest to me to do ?
