when changing a VM VGPU policy to the General policy fails with error message:
"You need to select either sizing or placement compute policy."
This is a UI defect affecting VMware Cloud Director 10.4.2.x and 10.5 versions.
This is a known issue affecting VMware Cloud Director 10.4.2.x and 10.5 versions.
Issue will be resolved in a later release of Cloud Director.
For a possible workaround, please use the workaround provided in the Workaround section.
If your VDC has one or more custom VM sizing / placement policies assigned, a drop box appears where you can select either of those, but also the System Default one.
