Remote Console for Windows VM from custom Cloud provider

nolano — Mon, 15 Dec 2025 14:32:23 GMT

Hello,

I am trying to bring up a remote console in Morpheus for windows VM's. These run in a Cloud, in which the Morpheus integration comes from a separate plugin.

The error message: "Ambiguous method overloading for method com.morpheus.provision.CloudPluginProvisioningService#getPluginProvisionProvider. Cannot resolve which method to invoke for [null] due to overlapping prototypes between: [class com.morpheus.ComputeServer] [class com.morpheus.Container] [class com.morpheus.Instance] [class com.morpheus.ProvisionType]"

I do not see any logs in guacd process, so I do not think it is a network issue. I think the issue is between Morpheus and the plugin.

Could I please get some info on what is needed in a Cloud Provider implementation for windows vm console access? So that I can try to determine what is missing in our plugin.

More specifics of our setup:

Morpheus 8.0.11

These are Windows VMs in containers running on rke2 using kubeVirt.

Full error and stack trace:

This error was caused by the ProvisionProvider returning a code which did not match with the Cloud Provider.

The fix was to ensure both implementations returned the same string.

CloudProvider getDefaultProvisionTypeCode()

ProvisionProvider getCode()
