[SOLVED] kernel panic on install rocky Linux

[frankz]

Hello to all . I have tried install the distro rocky linux , but i see persistent error kernel panic !

 

[cheiss]

I guess you mean while installing Rocky Linux in a VM?
Can you provide a copy (or screenshot of the console at least) of the kernel panic?

Thank you for responding, yes during installation.

Try with CPU-type: host:

Thanks it worked with CPU Host . I wanted to insert it in the HA groups, I hope that with this option it works on all nodes.

You could also try with CPU-type: max:

Hi , thanks for your reply but your answer whit max cpu value what does it mean ?

For the CPU-type, instead of choosing: host, you choose: max and see, if it also helps for the kernel panics inside your VM. If yes, this CPU-type (max) might help, if you encounter problems with live migration and CPU-type: host.
This is only a guess. You have to try. I only wanted to give an alternative, if you run into problems with live migration...

Thanks for yuor reply , i'am afraid wich you have reason in this case . infact when i migrate this machine , that VM is forced to shutdown . i have replace the parameter in menu cpu with cpu max and the migration is occurred on line . thanks for you helped .

Great, thanks! Worked for me as well
I had the same issue with this config :

FYI:
Not only was this PVE 7.2, according to the kernel version, either never updated: [1] (with the proper repositories: [2]) or since then not rebooted, but also is PVE 7 EOL: [3] and it is recommended to upgrade to PVE 8: [4].
