[Erwan RENIER <erwan.renier@xxxxxxxxxxx>]

As i had time to lose, i tested it and... it works :)
Well at least , it seems to work, the VM launch and i see no errors
be carfull to not use scsi_mod in the same time.

To change it, I think you can try to change this line in the kernel source : drivers/block/xen-blkfront.c
#define DEV_NAME        "xvd"   /* name in /dev */

But i think there is a good reason to it,
probably to avoid conflicts with the scsi driver,
so i'm waiting for your feedback :)

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,
