Imported VM Starts but Does Not Initialize the Display

Mefosheez

@stormi @kagbasi-ngc I have this same error in a separate thread, however, there is no nesting involved. from my limited knowledge, it seems like xcp is not seeing the available memory resources during boot and fails. if I migrate a running VM to the same host that gives me this error, it will operate as expected. but, after reboot... failure to launch.

@olivierlambert Thanks for your help so far.

@kagbasi-ngc Looks like we missed something, as the log indicates it loaded OVMF-release.fd:

Dec 13 13:54:59 VMH01 xenguest-2-build[8345]: Loaded OVMF from /usr/share/edk2/OVMF-release.fd

We'll come back to you with a better test procedure.

For now I just have a quick and dirty one, consisting in overwriting the release file with the debug one:

cp /usr/share/edk2/OVMF-debug.fd /usr/share/edk2/OVMF-release.fd

You can revert this change with yum reinstall edk2.

@stormi Sorry for the delayed reply. I did as you requested, and below are the resulting log files. I started the VM at timestamp Dec 17 14:43:34 and stopped it about 2 minutes later.

If I can be of assistance, don't hesitate to ask please. Thank you.

@kagbasi-ngc @Mefosheez We're trying to find developer time to diagnose the cause, but it's not the best time of the year, so I can't promise anything on delays.

@kagbasi-ngc Does your VM have a vTPM? If so, could you try without?

kagbasi-ngc

@stormi No worries at all, I understand.

@stormi Yes it does. I just deleted the VTPM and tried starting it, but no success. Still the same issue - can't initialize the display.

I also disabled Secure Boot, and got the same results.

@stormi thanks for the feedback. no rush here. just let me know if I can help.

@stormi I wanted to follow up. I saw a good number of patches available today, first updates since the issues started for me. I processed them, but this issue still seems persist.

I know this thread is about nested virt, and i don't want to derail that. this is where i had posted about the issue prior. I believe they are going to be tided to the same root. any help would be appreciated.

@Mefosheez I forwarded internally. Feel free to ask again after a week if no answer comes.
