Strange issue with booting XCP-NG
-
@danp said in Strange issue with booting XCP-NG:
https://github.com/xenserver/xen.pg/commit/4629bd92f3d3263da9d7fe304df422e54d56ee56
This seems present for XCP-ng 8.0 and 8.2..
-
@r1 Its still strange though that this problem still persists. As I think there are more people using the Quadro P400.. (Correct me if I'm wrong of course).
-
Do you guys think that this has to do with UEFI? Otherwise I will have to reinstall XCP-NG in BIOS mode instead of UEFI mode...
-
@appollonius I don't think it is driver issue (POST boot).. We may know more only from serial output.
Are you able to boot as-is in BIOS mode without reinstall?
-
@r1 I could try that, will update when that has been done...
-
@r1 How do I boot in BIOS mode without a reinstall? Can that even be done, because I remember that when I installed xcp-ng I had to choose between BIOS or UEFI am I correct? (Could be something else though) otherwise if not I can give that a try.
-
@appollonius I think it will depend on hardware settings. See if you have option to change the mode in motherboard settings?
I don't have physical hardware access to validate this as I mostly use nested virtualization but XCP-ng
/boot
has required files support both for UEFI and BIOS mode.Maybe @stormi can confirm.
-
@r1 If this could be confirmed I would be happy to test it, otherwise I'll have to do it when I have a new system.. Because I dont want to mess up the current one just yet
-
@appollonius I don't think there is any harm. You will be either be able to boot or not. You can always switch back to old settings.
-
@r1 Alright then I will give it a try somewhere today
-
Unless I'm mistaken, XCP-ng installed in UEFI mode won't boot in bios mode. There won't be anything written in the MBR.
-
@stormi Ahh... So I would have to reinstall XCP-NG completely to be able to boot in BIOS?
-
@appollonius yes
-
@stormi Damn... And that all to 'test' if the GPU is working in BIOS mode.
-
Maybe I asked the wrong question here, but is the NVIDIA QUADRO P400 even supported? Maybe that could be an issue as well? If not I think I'll have to grab something like a Radeon WX2100..
-
It's not supported for vGPUs https://xcp-ng.org/docs/compute.html#vgpu but it should not prevent other uses of XCP-ng in theory.
-
@stormi Ahh thanks for the webpage, though I still think BIOS mode wont fix this issue I believe.. So I will capture the serial output, to see what happens.
-
As I said (or tried to say), vGPU support has nothing to do with the ability to display the host console on screen.
-
So BIOS mode might help, but there's no guarantee.
-
@stormi I wanna try this first so I can see what is going wrong in UEFI mode. So I can pass it on to you guys, so you might be able to fix this issue in UEFI mode. Because there might be other people running into this issue as well
