Import .img in XCP/OpenXenManager

Hi there,

I'm trying to import an .img file to a XCP machine as a VM, using OpenXenManager. This doesn't work, because only .xva files can be imported. Now my question, is it posible to convert the .img file to an .xva file, or is there an way that the .img can be imported ?

My current running OS is Ubuntu 10.04, with a dual boot with win. 7.

(yes, i have used google allready.. )

Thanks! ,

Bart.
