created. The console snapshot:
this seems to be a bug of grub2 component in redhat, see: @neo954 , would you please take a look at the tickets above and obtain the updated grub2 with the fix ? |
@robin2008, need to recompile grub2 and test if it can work or not. |
Enclosed please find the recompiled
|
hi @neo954 , did you try whether the provision can complete with the updated grub? |
@immarvin, Yep, it was verified. But I am not sure if this issue is really solved. |
Tried to run
|
It seems it is not a grub2 problem. Since genesis can be booted successfully. |
Set the priority of this issue to low, since this issue cannot be recreated daily in the Jenkins autotest environment. Failed twice in the latest week. |
@tingtli @neo954 @immarvin , I do not think it was the problem which Could we put effort to resolve this ASAP? thanks

The default xCAT generated osimage
|
Tested on another PowerKVM guest. The default xCAT generated osimage ubuntu18.04.2-ppc64el-compute can be booted successfully.
BTW, the xCAT management node runs xCAT version
|
So, I suspect, this issue can be recreated on |
Patch was merged, patch was reverted. The priority was lowered, since this issue is only affected POWER9 KVM guest. For xCAT user who use bare-metal POWER 9 machine, the HWE kernel is desired. Thus, the test case need to be revised. |
The Ubuntu kernel problem will be tracked with #6338. |
I will close this one. |
xCAT 2.15 both on ubuntu18.04.2 and ubuntu16.04.5
node definition
From the console, get the following information
And from /var/log/message, no more data got after a DHCP request
From virsh console f6u13k15, no more output after get "/tftpboot/boot/grub2/grub2-f6u13k15"
==> So tftp problem, service tftpd-hpa restart fix this problem.
