+Kdump now works on live images with some manual configurations. Here is the step
+by step guide.
+
+1. Enable crashkernel reservation
+
+Since there isn't any config file that can be used to configure kernel
+parameters for live images before booting them, we have to append 'crashkernel'
+argument in boot menu every time we boot a live image.
+
+2. Change dump target in /etc/kdump.conf
+
+When kdump kernel boots in a live environment, the default target /var/crash is
+in RAM so you need to change the dump target to an external disk or a network
+dump target.
+
+Besides, make sure that "default dump_to_rootfs" is not specified.
+
+3. Start kdump service
+
+    $ kdumpctl start
+
+4. Trigger a kdump test
+
+    $ echo 1 > /proc/sys/kernel/sysrq
+    $ echo c > /proc/sysrq-trigger
