Hi gurus, 

The page 
http://wiki.xensource.com/xenwiki/XenParavirtOps says disk devices on domu are 
always /dev/xvdX. And I failed when I try to map a raw disk to domu with the 
name /dev/sdb. The line  ‘phy:sdb,sdb,w’ in domu config file doesn’t take 
effect. Actually I found
 a raw disk named /dev/xvdf on the domu. 
Anybody got any idea why xen4 put such restriction? How to map to other names 
such as /dev/sdb on domu? 

Thanks, 

HUAXIANG FAN

Maverick (10.10) will accept sdX from the xm config. Maybe Natty will too, but 
not Lucid or Karmic, which want xvdX.
