Thread-topic: [Xen-users] disk devices are always /dev/xvdX
Thanks Mark,
I used the domu kernel built from stable/2.6.32.x git branch. It seems only 
accept xvdX. Any workaround you can offer to rename xvdX to sdX? Otherwise, we 
might need to change our codes.

Thanks in advance

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? 

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