RE: General KVM/QEMU VM debugging techniques

Hi,
    We are observing a problem with CPU hotplug.

If secureboot option is enabled under UEFI  and then if we try to do CPU hotplug the VM crashes/just reboots.

No crash dump is generated, no panic message, just VM restarts. Issue seems like: 
https://bugzilla.redhat.com/show_bug.cgi?id=1834250

What are the debugging techniques we can apply to halt the VM and examine what's going on?
VM has been configured with crash dump.
