Ravi,
I install corekeeper and the core file is kept in /var/crash. But why not use
gdb to attach to the VPP process?
To turn on VPP vhost-user debug, type "debug vhost-user on" at the VPP prompt.

Initially '/proc/sys/kernel/core_pattern' was set to 'core'. I changed
it to 'systemd-coredump'. Still no core generated. VPP crashes
