I'd certainly like to see the unmap stuff, don't know about the locking stuff. I think there was a question over whether to support extended copy as-is or support an xcopy-lite that may be in the works. I thought esx was supposed to detect support and only use it if present (gleaned from watching marketing videos on youtube), it's not automatically disabling it, then? -- Andy
