I wish to find out how I can capture a kernel dump file when the VM running on Ubuntu 16.04 crashed/hanged. Below is what I have done so far.
- I installed
linux-crashdumpon the VM
I edited
/etc/default/kdump-toolsto include the line
USE_KDUMP=1
- The VM had been crashing/hanging frequently but I failed to obtain any dump file from
/var/crashfolder after I had to restart the VM through vCenter to access the VM's folder via putty. - The only time I can successfully retrieve a kernel dump file is when I simulate a kernel panic.
