VIO: kernel panic

Hello,

When we tried to start a VM instance Image(VMDK), just with OpenStack tool “nova boot”. But this results to a kernel panic.

How we can analyze/debug the below issue in VIO.


FYI.

Can anyone help on above request.

Thanks,

Maghesh

Can you provide us with some more information about this problem :-

VIO Version

Guest OS

How did you obtain this VMDK ?

What is the vmdk subformat (sparse, flat, streamOptimized) ? Can you paste the output of "head -20 <path_to_vmdk>" if it has a some header information. Otherwise, it should be a flat disk (a.k.a preallocated).

Finally, can you also upload the output of "glance image-show <image_id>" corresponding to your vmdk image.

Thanks, we will help you troubleshoot.

Please find details below:

The Image INFO.MEDIA.0463 is based on RHEL 6.7. It was loaded via glance. From this image a software volume was created and used as boot volume for the ssb instance:

There are 2 ways to make it work

  1. ​Update existed glance imageglance image-update <image name> --property hw_vif_model=VirtualVmxnet3 --property vmware_adaptertype=paraVirtual --property vmware_ostype=rhel6_64Guest​
  2. glance create new image with OVA

Looks like the VMDK has busLogic in its header but in order to boot this successfully you had to specify the controller type as paraVirtual.

I wonder how you created this VMDK ? Did you use any conversion tools to convert the disk from other formats or did you take this from an existing VM (which was working) ?
