Thread-topic: disk devices are always /dev/xvdX

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,
