pvmove broken? netbsd-6 (xen dom 0)

[Louis Guillaume <louis%zabrico.com@localhost>]

Hi,

I'm trying to get rid of a physical volume, replacing it with another. 
This appears to be a job for "pvmove". I added the new PV to the volume 
group and then attempted a "pvmove" to transfer the extents to the other 
disk. But it fails as shown below. Any help would be great:
