[Bug] xcp-ng -> pve unsupported XML-RPC protocol

[tuxpowered]

Describe the bug

When performing a cross-cluster migration from xcp-ng to pve (both on latest versions) an unsupported XML-RPC protocol error is displayed.

Steps to Reproduce

1. Join both PVE and XCP-NG clusters to Pegaprox
2. Right click on the desired VM to migrate and select cross-cluster migrate
3. Select network and stroage locations and click Migrate

Expected behavior

Would expect a progress or status showing migration task started, or an actionable error.

Environment

• PegaProx Version: Beta 0.9.13
• Installation Method: prebuilt ct image
• OS: Proxmox
• Browser: Firefox, safari
• Behind Reverse Proxy? No local installed on same network as both servers.
• UI? Corporate

XCP-NG -> Proxmox VE is simple not supported in this Option Cross Cluster Migration.

You need the Hypervisor Migration XCP -> Proxmox VE

@MrMasterbay Is this only available via the API ? or is there an option in the GUI? Because aside from the Cross-Cluster migration, i could not find any other reference to Cross-Hypervisor Migration.

NVM > I am blind. It is labeled "Hypervisor Migration"
