I am trying to generate a kdump file of a VM running Centos 7 (HVM) on Xenserver 7.
I followed the following steps.
xe vm-list name-label=<name> params=uuid --minimal
xe vm-param-set uuid=<vm_uuid> actions-after-crash=preserve
For HVM guests, run the following command on dom0: <<< I had to google correct command for this part
After running the crash command the VM halts and no dump file ever gets generated....
Per the link Preserve should "leave the VM in a paused state (for analysis)" but the VM just halts/shutsdown
Can anyone help with this? Or is there something else I need to do to setup kdump on Xenserver 7 for VMs?
