With an awareness of virtual
machine adds, moves, and deletes within a Google VPC, you can create
Security policy rules that automatically adapt to changes in your
application environment. As you deploy or move virtual machines,
the firewall collects attributes (or metadata elements). You can
use this metadata for policy matching and to define Dynamic Address
Groups (see Use
Dynamic Address Groups to Secure Instances Within the VPC).
can configure up to ten VM information sources on each firewall
or on each virtual system on a firewall capable of multiple virtual
systems. Information sources can also be pushed using Panorama templates.

an update takes up to 60 seconds plus the configured polling interval.

Verify the connection status.
If the connection status is pending or disconnected, verify
that the source is operational and that the firewall is able to
access the source. If you use a port other than the Management (MGT)
port for communicating with the monitored source, then you must
change the service route (select
