Hi all,<br /><br />we have used the latest stable release (tag: edk2-stable202302) of edk2 to build OVMF.fd. Then used this OVMF.fd to create our WIN10 guest. <br />
<ul>
<li>QEMU launch parameters: qemu-system-x86_64 -accel kvm -cpu host -drive file=img_KVM_Boot_EFI_WIN10,if=none,id=virtio-disk0 -device virtio-blk-pci,drive=virtio-disk0,bootindex=0 -m 4096 -smp 4 -bios OVMF.fd -daemonize -vnc :7</li>
<li>Check command: systeminfo</li>
</ul>
After checking the BIOS version, we have seen the unknown EDK II version description issue:<br /><img src="cid:attach_0_174A5B189349C1BD_26451@groups.io" /><br />Compared with previous commit id:&nbsp;<span style="color: #172b4d; font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, 'Fira Sans', 'Droid Sans', 'Helvetica Neue', sans-serif;"><em>ca33daafc630a7952de482813dccd5202f005dbf</em>, the BIOS Version shows as "<strong><em>E</em></strong></span><strong><em><span style="color: #172b4d; font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, 'Fira Sans', 'Droid Sans', 'Helvetica Neue', sans-serif;">FI Development Kit II / OVMF 0.0.0, 2/6/2015</span></em></strong><span style="color: #172b4d; font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, 'Fira Sans', 'Droid Sans', 'Helvetica Neue', sans-serif;">".

Thanks.<br /><br />Best regards,<br />Ruifeng</span>
