Thank you for the post @PAFrank

This looks like compatibility issue. For ESXi 6.7 the minimum supported PAN-OS version is 8.1: https://docs.paloaltonetworks.com/compatibility-matrix/vm-series-firewalls/vms-series-hypervisor-sup...

Is version you are running 8.0 or 8.1?

Kind Regards

Thank you PavelK for your nice explanation. 

The version is 8.1.x. I forgot what is the x.

Then , based on the document you mentioned above, I tried  version 8.1.3.  it can work, but it is vey unstable. 

Is the latest version better, such as 9.x ?

Thank you

Thank you for reply @PAFrank

Yes, I would recommend to move to version 9.1.X.

Kind Regards
