README

This repository contains the yang modules, VCI service and packaging for vyatta-kdump feature.

vci-kdump

• vci-kdump implement the VCI configuration, state, and rpc services for vyatta-system-crash-dump-v1 yang module. vci-kdump creates the required configuration files for kdump-tools service and launches the systemd kdump-tools service. On normal boot kdump-tool.service uses kexce to load the crash dump kernel. When booted in the kdump kernel after a crash, it uses makedumpfile to capture the vmcore and save it to a file in /var/crash directory. The backend code reside in internal/kdump/kdump.go.
