Hi, SupreetK ,the HungVM-> Send_NMI_To_Guest is not works in ESXI 6.0,

is it disabled in ESXI 6.0? how to enable it?

thanks.

lihlcnkr​ It should work even for 6.0. Alternatively, run the below command. More details in the link - VMware Knowledge Base

vm-support --performance --manifests="HungVM:Coredump_VM" --groups="Hardware Logs Network Storage System Userworld VirtualMachines" --vm="/path/to/vmx"
