Hello:

In the environment of PXE and Http server setup configured in same Linux 
machine HTTP Boot is gettin failed. If the PXE Server and HTTP Server 
configured in two different machines then the boot is fine.


Failure Test case:

1.Select PXE IPv4/6 to boot

2.Booted into Grub Boot loader File successfully, then exit back to setup from 
grub boot loader

3.select HTTP IPv4/6 to boot -> HTTP boot FAIL



Root Cause: When Pxe boot is successfully booted to grub, All network drivers 
are stopped,

And when we select Http Boot , All network drivers are getting started again, 
but Dhcp->start interface is failed with EFI_NO_MAPPING



As EFI_NO_MAPPING is reported from Dhcp->start ,we have suspected link local is 
not updated properly. Hence added few seconds delay before starting http boot 
and Http Boot is working properly.



Pass test case:

Select HTTP IPv4/6 to boot into Grub boot loader file, then exit back to setup 
from grub boot loader console

then -> select PXE IPv4/6 to boot -> PXE can boot PASS



When http boot is successfully booted to grub, Network Driver are not stopped.  
Since the drivers are not stopped,  when we select Pxe Boot it is working as 
all network drivers configured the instance properly.



For this test case #1 is there any recommendation to address the issue 
generically without havin hardcoded delay before HTTP Boot?


Thanks

Siva
