Donal Lafferty commented on CLOUDSTACK-3377:
--------------------------------------------
Problem due to incorrect serialization in system VM being used. Previously,
the JSON serializer encoded object types using the type's simple name. Now it
is using the type's fully qualified name. Thus, the system VM should be
returning "com.cloud.agent.api.StartupProxyCommand" and not
"StartupProxyCommand". Therefore, the system VM in use needs to be updated.

> com.cloud.agent.transport.ArrayTypeAdaptor@697537aa failed to deserialize

> Workaround :
> ==============================
> 1. I tried removing the tags from the host and then restarting the MS, but it
> didn't work and i still saw those errors.
> 2. Reboot the XenServer host, this works.
> NOTE : This is a RPM setup not Dev setup
