Here's a quick link to some of my code for XCP: (last updated Nov 24, 2025)

for XCP 8.3 r8125-module-alt-9.016.01-1.xcpng8.3.x86_64.rpm

Realtek r8126 driver. This 8126 driver REQUIRES the above r8125-module-alt as the standard 8125 driver conflicts with this driver.

for XCP 8.3 r8126-module-10.016.00-1.xcpng8.3.x86_64.rpm

Realtek r8127 driver. First release, only basic testing done (does not require new 8125/8126 driver).

for XCP 8.3 r8127-module-11.015.00-1.xcpng8.3.x86_64.rpm
At this time, all updated Realtek firmware is not included with XCP. Cards should still work with default firmware.
Current official rtl_nic firmware can be downloaded from kernel.org

The new XCP installer ISOs for 8.3 and 8.2 will include needed fixes and updates to boot new machines that had the UEFI problem before.
It's recomended you use the new official XCP installer ISO.
Note: If you manually delete the drivers you'll need to issue the "depmod -a" and "dracut --force -M /boot/initrd-$(uname -r).img $(uname -r)" commands.
