Thanks for the info. Yes. xvdX works. I tried the following config. 
disk = [ 'file:/var/images/min-el3-i386.img,hda,w', 
'file:/var/images/data.img,xvda,w' ]
and I can mount /dev/xvda in HVM domain using PV driver.

One remaining issue is that: PV driver still complains "register_blkdev: cannot 
get major 3 for ide", since it will try to connect /dev/hda. This error message 
is confusing to user, althouhg it actually do no harm. 

Best Regards
Ke
