It's possible that the issue lies within VMware Workstation.

Danp

Have you attempted to analyze the exported file using qemu-img?
For example:

qemu-img info file.vmdk
qemu-img check file.vmdk

Danp

Ah... ok. I think I originally checked the VM export.

This could be a bug. Does it occur with all VDIs? What happens if you try to import the file back into XO?

Danp

@abudef What steps are you performing to export the VDI as a VMDK?

gskger

@coolsport00 Yes, I am using the GPUs with llama-swap to serve qwen3.8-27b and qwen3.6-35b for local inference with Bifrost as an AI gateway for local and cloud AI provider. Never tried vGPU myself.

Danp

@jcdick1 Ideally you should open a ticket via the Support Portal and provide the tunnel ID there along with a link to this discussion.

Danp

@jcdick1 We can take a look using the support tunnel of your XOA instance.

Danp

Have you check the status of the nodes and for faulty resources?
