- The PXE booting did not respect the specified boot order when multiple NICs of the same type were configured for a virtual machine. Instead, the gPXE image attempted to boot from all NICs supported by the loaded image in the PCI bus scan order. This resulted in boot delays, attempting to perform a PXE boot on unintended devices, as well as in booting from unintended devices in case of success. This update provides the gPXE boot image with the PCI address of the intended boot device, ensuring that the image only attempts to boot on the intended device.
- HTTP requests generated by gPXE set wrong TCP flag (SYN & PSH) in the first packet of a session. Consequently, when using a firewall, the TCP packet flow would be blocked and the HTTP module integrated with gPXE would not work. With this update, gPXE no longer set the PSH flag in the first packet of a session and the system now boots as expected.
