Hmmm, I start all my PVs with xm create, I wasn't even aware that there was a new option :-( I also created the hvm the same way which is why I was surprised by the different behavior.

Ooops my error, it is the hvm I am having trouble with the CD on.

Hmmm, must be a better way to do this.

With VMware, I used to mount the iso via a symlink and then used to do a disconnect, relink to a different iso, connect again to change the CD. But I am not sure how to do this with an HVM. At the moment, I have virt-manager telling me that hdc is there and windows telling me its not. :-(
