Unable to capture memory dump of the instance running on Open Stack

Solution In Progress - Updated -


  • Its Open Stack setup. unable to ssh the instances but pingable without any issue. security gorups are fine. So, to findout the cause if we try to capture vmcore with virsh command, it fails:
virsh dump --memory-only instance-000012f6 /tmp/instance-000012f6.core
  • But it just hung & produced no output.
