[ovirt-devel] Error: VDSGenericException: VDSNetworkException: Policy reset

[Piotr Kliczewski]

Martin,

This is policy reset when we perform setupNetworks. This is expected
behavior but the stacktrace is confusing and we have a BZ [1] to
improve it.

The reason for it is that engine makes sure to keep connection alive
at all times by using heartbeats. When we are about to configure
network
we know that there will be connectivity issue so before performing the
operation we change heartbeat policy to ignore missing heartbeats.
This operation enforces to reconnect using different policy and we see
this nice stacktrace in the log.

Thanks,
Piotr
