Can someone provide some guidance with my server, I have a fairly new
centos 8 server, pretty much just a KVM host but I have noticed that its
dumping and rebooting at various times. Journalctl does not go back past
the reboot so I am unable to catch what may be causing it, it appears to be
KVM from /var/log/messages and it appears I should have a kernel dump file
but I am unable to find it. I had these same kvm images running on the
centos 7 server for over a year at a time, not sure what is making things
less stable.
Any help would be appreciated, thanks.
Here is the output from /var/log/messages:
