@olivierlambert

Just had two consecutive crashes 15 minutes apart.
This is comparison between old crash before updates and after latest updates.

@olivierlambert said in Kernel panic on fresh install:

Okay so now you have the updates really installed, we'll see if it happens

Just got crash reboot again, while trying to restart a VM from XCP-center from another VM in the pool. This reboot should apply all patches from last updates.

@olivierlambert these events helped me finally stop supporting OpenVPN and I'm not going back Wireguard works much better for my setup. Thank you!

A little update on this. I deactivated the OpenVPN server on OpnSense in December and since then there have been no reboots or kernel panics.

@Danp said in Kernel panic on fresh install:

@sasha BIOS is still outdated on your new hardware.

Agree. But I can't do anything about it

Got similar crash today on new hardware

[ 484188.752631]  EMERG: Kernel panic - not syncing: Fatal exception in interrupt

@payback007
Thank you for sharing this. So far this is the one simple and reliable way to start VM in the desired order.

@tuxen said in Kernel panic on fresh install:

@sasha It's worth notice that the BIOS (from 2019) is relatively old/outdated. It's recommended to update the BIOS to a more recent version.

Thank you for pointing out! I'll try to reach support team for this.

@olivierlambert
I would love to! Only thing I can say - is when I was using windows XCP-console from VM inside the pool, once starting VM caused whole system to crash with this error, another day changing VAPP config also crashed server. That is why I am trying to avoid using xcp-console during business time. I'll try to reproduce it once again and reply.

New crash, same message...

@olivierlambert

Just had two consecutive crashes 15 minutes apart.
This is comparison between old crash before updates and after latest updates.

@olivierlambert said in Kernel panic on fresh install:

Okay so now you have the updates really installed, we'll see if it happens

Just got crash reboot again, while trying to restart a VM from XCP-center from another VM in the pool. This reboot should apply all patches from last updates.
