XEN: kernel dump is not working correctly on Dom0

After triggering kdump on Dom0, system just freezes and nothing happens even after long time.


It is important to verify whether the default kernel is installed on the machine as kdump is working with default and not with the Xen kernel:

systemDom0:~ # rpm -qa | grep kernel                                                                                                                                       

When default kernel is missing, please install appropriate default kernel version and trigger the kdump once again.


Kdump is using the default kernel to generate a dump.
