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. Nucleodyne at Nutanix 408-718-8164
